"Yeah, the more and more you run on it the better, the more confidence you build on it," Foster said. "I guess, with this type of injury -- I talked to the doctor that cut me open. He said the best rehab is actually getting out there and playing. He feels confident that the attachment is going to stay there, so that helps."
Foster has not played yet this season since tearing his groin on Aug. 3 during the Texans' first fully padded practice of training camp. Foster is listed as questionable on the injury report, marking the first time all season Foster has not been ruled out on a Friday for a Sunday game. Though he felt positive about his progress, he said he will have to see how he feels Sunday.
Foster was listed as limited on the Texans' injury report earlier this week.
"I have no idea what that means, actually," Foster said. "Limited, like, if you're out there, you're out there. I understand when you're first coming back, you don't want to do all the drills, but I'm a full participant in practice."
The Texans will face the Atlanta Falcons on Sunday and then play a division game against the Indianapolis Colts at home on Thursday night. If Foster plays in both, that would mean two games in five days.
"I don't think it can factor in," Texans coach Bill O'Brien said on Monday. "I think we've got to do whatever we've got to do to win this game. We're not thinking about the following game; we're thinking about this game."
The thought has crossed Foster's mind.
"It's a business, so all that gets taken into consideration," Foster said. "We're cognizant of that, and we'll move forward accordingly."
If he returns, it would be the first time Foster has played a game with quarterback Ryan Mallett. Foster was injured for both of Mallett's starts with the Texans in 2014.
"We've never had a chance to ride together," Foster said. "I feel like he has a really good command of the offense. You can tell it's just very smooth when he gets out there because he's been there for so long and he commands it. When you have players like that who are confident in what they're doing ... it's going to be fun."
