Foster sustained the injury during an Aug. 3 practice and underwent surgery four days later to repair a torn groin muscle. Foster hoped to recover in less than three months.
Head coach Bill O’Brien said he was optimistic for Foster’s return “sooner rather than later” earlier this month.
Foster, 28, ran for 1,246 yards last season with 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.
