The Houston Texans aren't completely sure what the timetable is on RB Arian Foster's hamstring injury but they, along with the fantasy football world, are hoping Foster returns to the field soon. 

The good news is that, according to John McClain of the Houston Chronicle, Foster isn't expected to miss the first week of the season against the Indianapolis Colts.

Since the Texans returned from San Francisco, Foster hasn't been limping. He's been jogging at two practices. They left him behind to rehab rather than make the trip to Minnesota for the last preseason game.

I've talked to just about everyone about Foster's hamstring, including Foster, and I expect him to play against the Colts.

The bad news is that ESPN disagrees. John Clayton suggests Foster won't be in the Week 1 lineup.

Arian Foster tweeted his hamstring MRI and it sure doesn't look like he's been in the lineup when the season starts. He has a tear.    

Who to believe? I'm not quite sure but we're about 10 days from finding out.

The problem is that hamstring injuries are the type of thing that can linger all season so you want to be careful in how you rehab from it. Foster already tweeted out a picture of his hamstring so you can expect opposing defenses realize that, and potentially plan to target that. 

So the Texans need to be careful in how they proceed. Check out Battle Red Blog for the latest on ESPN's report.
