Texans RB Arian Foster sat during practice and is a gametime decision

Houston Texans running back Arian Foster sat out during Thursday's practice, according to the team's official practice report. Foster, who has been dealing with a groin injury since Week 9, was limited on Wednesday after missing last Sunday's game against the Cleveland Browns.

Texans head coach Bill O'Brien is calling Foster a game-time decision for Sunday's game against the Bengals.

"It’s something that we’re going to have to see right up until game time," O'Brien said Thursday at NRG Stadium. "No setback. Just it really is, from one day to the next, just see how he’s doing and I'm sure we'll have to make a decision on game day. It’s just something that we've got to wait it out and see if it gets better."

If Foster is unable to play, rookie running back Alfred Blue will start. Blue posted 156 yards rushing during last week's win over the Browns, with a franchise-best 36 carries.

Blue is Jeremy Hill's former teammate, they spent two seasons together at LSU.

"We had some great times," Blue said. "It will be exciting to compete against him. We were close. We’re still very close. We stay in touch. In the offseason, we’ll try to link up and maybe train together in Baton Rouge.

Houston's rushing offense ranks third in the NFL and first in the AFC, averaging 144.6 yards rushing per game.
