HOUSTON -- When the Houston Texans host the Tennessee Titans on Sunday, it will be the first time since 2010 theyll play without J.J. Watt.A person familiar with Watts condition said the star defensive lineman he had back surgery Thursday and it is expected to miss the rest of the season. The person spoke to The Associated Press on Thursday night on condition of anonymity because the team hasnt announced the surgery.Watt was placed on the injured reserve Wednesday. Its his second back surgery in two months after he missed training camp and Houstons four preseason games after surgery in July to repair a herniated disk. He will miss a game for the first time in his career after starting 83 straight games since he was drafted in 2011.Watts loss is a huge blow to a team looking to bounce back after a 27-0 loss to New England last week. The Texans know that one person cant replace what Watt brought to their team, but coach Bill OBrien expects everyone to pitch in to help make up for his absence.OBrien was with the Patriots in 2008 when they went 11-5 despite playing without Tom Brady for all but one game.Ive been around teams where a top player goes down and the mentality of the team, which needs to be the mentality of a team, is that if a good player goes down -- if any player goes down -- the next guy has to step up, he said. Thats the mentality of this team.Defensive coordinator Romeo Crennel wouldnt say who would start in Watts place. But he did say that other stars of his defense like Jadeveon Clowney and Whitney Mercilus will have to continue to improve to keep the defense afloat.Tennessee coach Mike Mularkey said their game plan wont change with Watt out and knows Houstons defense has plenty of other threats the Titans will have to deal with.They have a pretty good front there, so we have a lot of guys we have to handle up there, he said.The Titans have struggled against Houston the past two seasons and have lost four in a row in the series. Tennessee defensive tackle Jurrell Casey knows that if they hope to contend in the AFC South theyll have to figure out a way to beat the Texans.Its something thats been haunting us for the last couple years ... its a ... divisional opponent thats been on top of our division for a long time, he said. If we want to take our division by storm, its got to start this week.Some things to know about the Titans-Texans game:ROAD WARRIOR: Marcus Mariota has been at his best away from Tennessee so far in his young NFL career. In seven games on the road, Mariota has thrown for 1,612 yards with 12 touchdowns with only two interceptions for a 104.9 passer rating. He also has a rushing TD and caught a TD catch on the road. This will be his first game in Houston, and Mariota has five TD passes with a 92.6 passer rating in his last three games against divisional opponents. Mariota isnt sure why hes played so much better on the road, where three of his four career victories have come.Thats going to have to change, Mariota said. Really, again, Ive got to continue just to prepare like any other game, focus on what I have to do and what this team asks me to do, and just continue to be a better player each and every single day.NO EXCUSES: Houston quarterback Brock Osweiler is in his fourth year in the NFL, but spent most of that time as a backup and has just 10 career starts. Hes struggled so far this season, throwing four interceptions and three touchdown passes. He isnt using his inexperience as an excuse.I dont use my lack of starts as an excuse for anything, he said. I expect myself to play at an extremely high level. I have great confidence in my abilities and what I can do, and I have great confidence in the teammates around me to help me do my job. Im never going to use my lack of starts for an excuse or say: `Ill figure it out eventually or anything like that.OFFENSIVE BOOST: The Titans are hoping tight end Delanie Walker is back against the Texans; he missed the Oakland game with a right hamstring injury. He had a career season last year with 94 catches for 1,088 yards, and Walker has been the Titans biggest deep threat so far, with the longest reception this season at 32 yards. Barring a setback, wide receiver Kendall Wright also should make his season debut in Houston. Wright caught Mariotas first career touchdown pass but has been hampered by injuries over the past season. His return would provide a speedy boost to the offense.RETURNING TO HOUSTON: This will be the second straight season Andre Johnson has returned to the town where he played his first 12 NFL seasons and still keeps a home. Johnson had six catches for 77 yards and two TDs when he played the Texans as a member of the Indianapolis Colts last season, and he said its fun to go back home.Itll be good to go back and see some faces I havent seen in a little while, Johnson said.---AP Sports Writer Teresa Walker contributed to this report.---AP NFL website: www.pro32.ap.org and http://twitter.com/AP-NFL Scarpe Balenciaga a Poco Prezzo .

For more than a decade and a half, my typical work week is hard to explain. Especially the part of keeping an eye on chiseled men taking center stage and stripping down to bikini briefs. A Chippendales consultant, Im not. Boxing weigh-ins are unlike anything else in sports. Calling fights week after week on national TV fosters an appreciation for them, the texture and passion of the sport is why its one of Hollywoods all-time favorite storytelling crutches to lean on. At least parts of it are.The overused late-round drama crescendo is an easy go-to for directors. But the day before the fight weigh-in? Its mostly ignored. Or its dismissed as a convenient scripted smack-talk moment.Then comes the 2016 biopic Bleed For This, the story about former five-time champion Vinny Paz. In what is as authentic a scene I have ever enjoyed in a fight film, native New Yorker Ben Younger perfectly captures the weigh-in for Pazs fight against Roger Mayweather 26 years earlier. He gets it. His film gets it.Forget the hackneyed approach to rating a boxing flick. You know the sports fan review where bona fides are based on how valid the in-the-ring action looks. Although it is quite good, it doesnt need to apply here.What Younger and his team were able to do in the opening 10 minutes of Bleed For This impressed me. It drew me in. It revealed enough of the world champion Paz t
