JACKSONVILLE Anthony Castonzo Jersey , Fla. — This season’s first AFC South rematch looks like a mismatch.The surging Indianapolis Colts have averaged a little more than 33 points over their last eight games while the reeling Jacksonville Jaguars have topped 21 points once in the last two months. The Colts (6-5) have won five straight since a less-than-ideal start. The Jaguars (3-8) have dropped seven in a row since thumping the New York Jets to end the season’s opening quarter.“Definitely dumbfounded,” Jacksonville defensive tackle Malik Jackson said. “If you would have told me in April we’d be 3-8, I’d say you’re lying. I don’t know what’s going on. … I don’t know what to say, what to change. We work hard. Guys have bought into the scheme. The locker room is still together.“Nobody’s waving (goodbye), nobody’s searching for flights to get out of here at the end of the season. Guys are locked in. To go out there and keep losing, it’s unexplainable. I don’t even know what to say to you.”The teams played three weeks ago, with the Colts winning 29-26 thanks partly to Jacksonville receiver Rashad Greene‘s fumble in field-goal range with 1:30 remaining.Jacksonville won’t look the same in the second meeting.Coach Doug Marrone fired offensive coordinator Nathaniel Hackett and benched quarterback Blake Bortles this week, making two major changes in hopes of jump-starting one of the league’s worst passing attacks. He promoted quarterbacks coach and former CFL head coach Scott Milanovich to play-caller along with backup quarterback Cody Kessler. Kessler, who went 0-8 with Cleveland in 2016, will make his first start in two years.Those tweaks could provide a spark for Jacksonville and might be a challenge for the Colts.“I have been in the situation before on the other side where we have had a quarterback change, whether it be by injury or you are just changing,” Colts coach Frank Reich said. “In my experiences, it’s not quite as big of a deal as everybody thinks.“It’s usually not as big a systematic change as people might think. You nuance a couple things, you shift a couple things, but mostly you are running your system. So he will be ready. He’s been running their system, right? He’s been running their system, been in it, so we will just prepare against what we have been seeing on tape.”Indy won’t have to prepare for Jacksonville’s best offensive player. Running back Leonard Fournette was suspended one game without pay for leaving the sideline, running across the field and instigating a fight at Buffalo last week. The penalty will cost Fournette about $100,000.Former Browns running back Carlos Hyde is expected to start in place of Fournette.Jacksonville also will be without left guard Andrew Norwell (ankle), who became the third offensive line starter and fifth lineman to land on injured reserve.“We’ve had some injuries,” center Tyler Shatley said. “You hate to see that.”The Colts know the feeling Ryan Kelly Color Rush Jersey , having played all of last season without quarterback Andrew Luck and losing by a combined score of 57-10 in two games against Jacksonville in 2017.Now, Indy is going for its first six-game winning streak since 2009, and Luck has three or more touchdown passes in eight consecutive games.“You work together and you should be getting a little better every day,” Luck said. “It’s great to see it show up on the field, but we know as the season goes on, the challenge gets a little bigger and the climb gets a little tougher.”TIGHT SPOTNo team has been more proficient finding tight ends this season than the Colts.Eric Ebron already has 11 touchdown catches, matching his total from the previous four seasons combined, and he’s tied for the league lead with Antonio Brown and Tyreek Hill. In fact, Andrew Luck has thrown 18 of his 32 TD passes to tight ends — more than twice as many as any other team.PENALTY PROBLEMSThe Jaguars are hoping to play a little cleaner. They lead the NFL with 22 personal fouls, and Marrone has grown tired of all the flags for undisciplined behavior.“The way the team plays is a reflection on me,” Marrone said. “I understand that. I’ve always taken a lot of pride in having a well-disciplined, smart football team and obviously, I’m not getting that done.”HOLDING THE LINEThe biggest turnaround for Indy has come on the offensive line. The Colts have given up just 11 sacks all season, matching New Orleans for the league low heading into Week 13, and have allowed just one over the last six weeks.100<button class="view-gallery">View Gallery</button> Gallery:View from the sidelines: NFL cheerleaders 2018Raj Mehta-USA TODAY Sports | Raj Mehta HOUSTON (AP) — A year ago at this time Andrew Luck was at home struggling with an injured shoulder that cost him the entire season.On Saturday he wrote a happy ending to the latest chapter of his comeback season, throwing for 222 yards and two touchdowns and the Indianapolis Colts raced out to a big lead and cruised to a 21-7 win over the Houston Texans in the wild-card game.Article continues below ...Luck put on a show in his hometown in a stadium where he’d attended games throughout childhood and played in them since high school, throwing for 191 yards and two touchdowns before halftime to help the Colts (11-6) build a 21-0 lead.He denied feeling “at home” at NRG Stadium, but admitted to having warm feelings for the city he grew up in and where his grandparents and many friends still reside.“But it’s still an away stadium,” he said. “It was very loud, very energetic, but fun to win, certainly.”Running back Marlon Mack had 148 yards and a touchdown for Indianapolis https://www.coltsfanshop.com/Margus-Hunt-Jersey , which advances to face the top-seeded Kansas City Chiefs in the divisional round next weekend.“We know we have an elite quarterback and we can throw it for 400 and win when we have to,” Indianapolis coach Frank Reich said.“But the margin for error in playoff football when you try to do it that way is very thin. When you can win like this — running the football and stopping it — that’s just everything.”Houston (11-6), which overcame a 0-3 start to win the AFC South, gave up too many big plays and couldn’t get anything going on offense in the first half to fall into the huge hole.Deshaun Watson, who was sacked an NFL-leading 62 times in the regular season, was sacked three times and hit eight more times in a disappointing playoff debut. He finished with 235 yards passing with a touchdown and an interception.“Just a lack of execution on our part,” Watson said. “We didn’t make plays. I didn’t make plays. Communication was a little off. You just got to give the Colts the credit.”The Colts, who opened the season 1-5, continued an impressive run by winning their fifth straight and for the 10th time in 11 games. Saturday was their first playoff appearance since the AFC championship game loss at New England in the “Deflategate” game in the 2014 season.It was another good game in a splendid season for Luck. He threw for 4,593 yards and 39 touchdowns in the regular season after missing all of 2017 with a shoulder injury.The Texans didn’t score until rookie Keke Coutee grabbed a 6-yard touchdown pass to cap a 16-play, 89-yard drive that included a fourth-down conversion that cut it to 21-7 with about 11 minutes left.They led the NFL with nine comeback wins this season, but their attempt at a rally ended on their next possession when Watson’s pass on fourth-and-10 from the Indianapolis 24 fell short with about four minutes left.Luck threw for 863 yards with six touchdowns as the teams split two meetings in the regular season. He picked up right where he left off in this one, when he found Eric Ebron on a 6-yard TD pass on their first drive. That play was set up by a 38-yard catch by T.Y. Hilton, who had 63 yards receiving on that drive.“We didn’t have a lot of guys that made the playoffs so the guys that made the playoffs wanted to go out there and set the tone early, try to get the crowd out of the game,” Hilton said. “That’s what we did.”Hilton didn’t have any catches on the next drive, but the Colts still drove down the field easily and made it 14-0 on a 2-yard run by Mack later in the first.Houston went for it on fourth-and-4 from the Indianapolis 45 on its second possession and Watson was intercepted by Kenny Moore II. It was his first interception since he threw two against the Redskins on Nov. 18.The Colts got to the 17 after that before J.J. Watt deflected Luck’s pass and he was intercepted by Brandon Dunn. But the Texans couldn’t move the ball and had to punt.Indianapolis pushed the lead to 21-0 when Luck connected with Dontrelle Inman on an 18-yard touchdown pass in the second quarter.“It’s very frustrating when they’re able to execute and get their job done,” Watt said. “We had a couple of big penalties early in the game as well. But you have to overcome it and you have to find a way to win.”The Texans had a fourth-and-1 from the 9 late in the second quarter and went for it again instead of settling for a field goal. The gamble didn’t pay off when Watson’s pass to DeAndre Hopkins was low and bounced in front of him in the end zone.INJURIESColts: Safety Malik Hooker left in the third quarter with a foot injury. … S Mike Mitchell injured his calf in the third quarter and didn’t return.Texans: Safety Justin Reid injured his ribs in the second quarter and didn’t return. … Hopkins said he played most of the game with a Grade 3 AC sprain of his right shoulder after injuring it in the first half.UP NEXTColts: Travel to Kansas City where the Chiefs were 7-1 in the regular season.Texans: The Texans have some decisions to make in the offseason with defensive end Jadeveon Clowney and safety Tyrann Mathieu both becoming free agents. They might use the franchise tag to keep Clowney, who was the No. 1 overall pick in the 2014 draft.
