John McClain of the Houston Chronicle reports that Foster is expected to be placed on the short-term injury reserve list. He can return after the first eight games of the season.
Foster appeared to injure himself on a pass play during Monday's practice. While Houston coach Bill O'Brien downplayed the injury, there were multiple reports the groin injury could be serious and cause Foster to miss a significant portion of the regular season.
According to Ganguli, Foster will seek a second opinion on his injury from Dr. William Meyers, who treated Texans linebacker Jadaveon Clowney's groin issues last season.
Foster ran for 1,246 yards and eight touchdowns in 13 games last season. He also caught 38 passes for 327 yards and five scores. In six seasons with the Texans, Foster is a four-time Pro Bowler.
