HOUSTON -- A person familiar with J.J. Watts condition said the Houston Texans star defensive end has had back surgery and will begin training camp on the physically unable to perform list.The person spoke to The Associated Press on Thursday night on condition of anonymity because the team hasnt confirmed the surgery or Watts roster status.Watt, the NFL sacks leader last season with 17 1/2, will miss the start of training camp, but is expected to be ready for the season opener.Watt spent most of the offseason recovering after having surgery to repair a groin injury in January.His performance last season helped the Texans to their first playoff berth since 2012 and gave him his second straight Defensive Player of the Year Award.The surgery was first reported by ESPN.---AP NFL website: www.pro32.ap.org and AP NFL Twitter feed: http://twitter.com/AP-NFLNike Vapormax Italia .25 million option on reliever Jose Veras.

ASHBURN, Va. -- Matt Jones will miss the rest of the preseason with a left shoulder injury, but the Washington Redskins hope their top running back will be ready for the start of the regular season.Coach Jay Gruden said Jones will be held out of the Redskins final two preseason games after spraining his shoulder Friday against the New York Jets. Gruden said Jones has already made significant strides since the injury and has high hopes hell be ready by the regular-season opener Sept. 12 against the Pittsburgh Steelers.We think the recovery time will be pretty quick, Gruden said Monday. He could be a little sore, but I think hes going to be fine.Jones ran for 490 yards and three touchdowns and caught another touchdown in 13 games as a rookie last season before going down with a hip injury. He became the Redskins No. 1 back after they let Alfred Morris leave for Dallas in free agency.The 23-year-old is getting stim treatments for blood flow and worked out on the sideline during practice Monday. He said he was feeling much better and isnt worried about missing out on game action.I dont feel like this is even a setback, because I take mental reps on the field, Jones said. It feels better knowing I did it in the preseason. Im not saying that preseason doesnt matter, I do want to still get better, but Ive got some time to get ready for the first game.Washington had little experience at the running back position even before Jones got hurt. He and third-down back Chris Thompson are the only players on the roster with NFL game experience, and the Redskins will lean heavily on rookies Robert Kelley and Keith Marshall and second-year player Mack Brown the rest of the preseason.Kelley replaced Jones as the top back against New York and could start Friday in the third preseason game against the Buffalo Bills.I think he and Keith will get the lions share of the carriees, Gruden said.dddddddddddd We want to see them in game situations against a good Buffalo team.Even if Jones is back by the opener, all eyes are on Kelley, an undrafted rookie out of Tulane, and Marshall, a seventh-round pick out of Georgia, to see what they can do. Teammates are impressed by their habits in practice, but Friday night at FedEx Field in the exhibition dress rehearsal for real games is a different animal.Im excited to see how they do, especially with a prime-time opportunity like theyre getting, said left tackle Trent Williams, whos set to make his preseason debut against the Bills after battling a sore right knee. We have a lot of faith in those backs. They show a lot of promise, theyve got a lot of talent, but obviously theyve got to put in the field on Friday and well have a better picture of it after that.Gruden has given no indication so far that Washington will look externally for running back depth, and Kelley, Marshall and Brown will get chances to keep it that way.Thats why were here, Kelley said. Thats why you have backups, for somebody to step up and take the place of that starter while hes down. When he gets back well be back doing our role on the team.Quarterback Kirk Cousins, who was held out of the Jets game to rest, recalled his own experience as a young player and hopes to help the young running backs Friday as they fill in for Jones.It stretches you as a player and its going to get you to where you need to be that much faster, Cousins said. I think its a really good thing for them. There may be some growing pains here and there, but thats what the preseason is for: to see what they can do, what they cant do.---AP NFL website: www.pro32.ap.org and AP NFL Twitter feed: http://twitter.com/AP-NFL ' ' '
