From yahoo sports : "Ahman Green was supposed to be the answer to Houston’s rushing woes when he joined the team last season.
Instead the former Green Bay back was limited to 70 carries for 260 yards as he dealt with a nagging knee problem.
The Texans signed free agent Chris Brown this offseason, but plan to rely on Green as the starter. Green, 31, says he’s past his injury and ready to play, but questions remain about his health.
“He looks good. He’s had a good offseason,” coach Gary Kubiak said. “I want to knock on something every time I say that. He’s been a good worker in the program. He hasn’t missed a day.”
The injury was first listed as a bone bruise and soon led to knee swelling. Numerous tests didn’t uncover any other injuries but the injury caused him to miss all or part of 10 games." http://sports.yahoo.com/nfl/news;_yl...v=ap&type=lgns
