Foster was reportedly injured during Monday night's practice after coming up limping on a pass play, according to ESPN's Adam Schefter. Texans coach Bill O'Brien told reporters it was a rest day for him and nothing out of the ordinary.
ESPN Radio's Jayson Braddock said Foster's injury was “serious” and that it “should require surgery,” adding that Foster could be headed to the injured reserve list, with designation to return. He would have to miss at least eight games if placed on IR.
The Houston Chronicle's John McClain reports that Foster should be able to return during the season.
Foster, 28, ran for 1,246 yards last season and eight touchdowns on 4.8 yards per carry in 13 games. He added 327 receiving yards and five touchdowns through the air. In six seasons with the Texans after going undrafted in 2009, he has made four Pro Bowls and led the league in rushing in 2010.
Running backs Alfred Blue, Jonathan Grimes and Chris Polk are listed behind Foster on the Texans' unofficial depth chart. Blue spelled Foster last season as a rookie, rushing for 528 yards and two touchdowns on 3.1 yards per carry.
