HOUSTON - The quarterback switch to Ryan Mallett didn't keep the Houston Texans from starting 0-2. They're hoping Arian Foster's eventual return reverses their fortunes.

Coach Bill O'Brien didn't rule out the star running back returning to the lineup this week. O'Brien said Monday that Foster (groin) is listed day to day ahead of the Texans' Week 3 home date against Tampa Bay.

Foster was injured during training camp and Alfred Blue, Chris Polk and Jonathan Grimes have taken his snaps by committee.

In three games, Polk leads the Texans in rushing with 19 carries for 60 yards. Polk rushed for 38 yards on 14 carries in the 24-17 loss to Carolina on Sunday.

No Texans tailback has a rushing touchdown in 2015. Foster rushed for 1,246 yards and eight touchdowns in 2014.
