HOUSTON -- As it turns out, the ' short-term lo s of No. 1 may be reflective of a long-term problem for the team.Second-year safety told NFL Media on Monday that Clowney said after suffering the injury that it happened after he landed on a "hole" in the turf at NRG Stadium. The retractable-roof domed facility has a natural gra s surface that is grown outside the building on Jamarcus King Jersey trays, which are brought in and pieced together to form the field.Coach announced Monday that Clowney on his knee and would be out four to six weeks."He told me on the field when it happened, he was just like, 'Bro, I just jumped, came down and hit one of the holes on the field,' " said Swearinger. "There are a few holes in the gra s, so he Deantre Prince Jersey said he thought he stepped on one of those holes and got hurt. So I told him to try and walk it off, see if he could go. He went in the next play and couldn't go, so I told him to go to the sideline and see what's up with it. And he went over to the sideline, and I gue s that's when they told him (he had to stay out)."Former punter Brett Hartmann SMG and the Harris County Convention and Sports Corporation, but not the team in 2012. The case has not been resolved.In January 2010, then- receiver blew out his ACL on the NRG Stadium turf, prompting coach to launch into very direct criticism of the Houston playing surface."The turf down there is terrible," Belichick said on Boston sports radio station WEEI-FM the day after the injury. "It's terrible. It's just inconsistent. It's all the little trays of gra s and some of them are soft and some of them are firm and they don't all fit well together, those seams. ... Some of it feels like a sponge, some of Phil Rollins Jersey it feels real firm and hard like the Miami surface. One step you're on one, the other step you're on another. I really think it's one of the worst fields I've seen."O'Brien was on Belichick's staff at the time. But when asked Monday if he had any problems with the turf, the coach's response was simply: "No. Nope." "It's just, from looking at all the angles on film, he just came down awkwardly," O'Brien said. "Most of those types of injuries are non-contact. When you look back at those injuries, they seem to be non-contact." Swearinger and Clowney played together at South Carolina, so the Tristan Bennett Jersey safety has known the rookie phenom for longer than any of his teammates."No. 1 pick, it was his first game, a lot weighing on his shoulders and he gets hurt," said Swearinger. "That's something that's tough to deal with. He'll get in training room, get in the cold tub, get all the treatment he needs to get himself back together. And we'll be good. ... He's gonna hit the ground running. An injury is the last thing anyone wants or expects, an injury that sits him out for a long period of time. It Joshua Bailey Jersey just tests your heart, to see where you're at mentally and physically."Former first-round pick is expected to replace Clowney in the lineup.Follow Albert Breer on Twitter .The latest covers the ' and action.
