Arian Foster is still "day-to-day", according to head coach Bill O'Brien.
"He did some things today," O'Brien said after Wednesday's practice. "I really believe its day-to-day with him."
O'Brien said Foster will work out before the Buffalo game, and the team will decide whether or not the running back can suit up against the Bills.
Foster was inactive last Sunday for the Week 3 matchup against the Giants. He was listed as "limited" because of a hamstring ailment on the injury report last Wednesday, Thursday and Friday.
On Monday, he said he "felt good" before Sunday's game, but ultimately wasn't able to go. Foster also explained that a hamstring injury can be tricky.
"I've played through a lot in this league and hamstrings are the hardest thing to gauge because you don't know how it's going to fatigue, how it's going to react to a certain cut," Foster said.
With a 55 carries and 241 yards through two games, Foster leads the Texans in both categories.
Rookie Alfred Blue started in place of Foster last Sunday, and averaged 6 yards per carry. Quarterback Ryan Fitzpatrick was asked about the possibility of getting Foster back for the Week 4 matchup against the Bills, and said he'd welcome the return of the six-year vet.
"He's obviously a special talent and you want all your guys to play every week," Fitzpatrick said. "If he goes, great. If he doesn't, I thought Blue did a great job with some of the runs and we're real confident with the guys behind him."
