HOUSTON (AP) -- A person with knowledge of the procedure says Houston Texans Pro Bowl running back Arian Foster, the NFL's leading rusher in 2010, has undergone arthroscopic surgery on his right knee.
The person, who spoke on condition of anonymity because neither Foster nor the team has publicly disclosed the details, called Wednesday's procedure "minor" and said Foster was already walking again.
The 24-year-old Foster rushed for 1,616 yards in his first full season starting for the Texans. The undrafted free agent who signed with the Texans in May 2009 also led the league in yards from scrimmage (2,220), rushing touchdowns (16) and first downs gained (123), all single-season franchise records.
The Texans had no comment on Foster's surgery, which was first reported by KRIV-TV and the Houston Chronicle.
