On Thursday, before a showing of the movie "Draft Day," Houston Texans running back Arian Foster said he is healthy, has been working out for a couple months and will be available for organized team activities.

It's great that Foster is feeling well, having had back surgery in November. At this point, that's obviously better than the alternative. But the real test of his health will come much later.

After all, recall that Foster entered last year's OTAs in great shape. Former Texans coach Gary Kubiak said at the time it might have been the best shape he'd ever seen Foster.

What followed was a difficult season for Foster, physically speaking. He had a calf injury in May that caused him to start training camp on the physically unable to perform list. He missed the preseason, but played starting in Week 1 of the regular season. Then on Oct. 20, Foster suffered a hamstring injury during a pass play that left the Texans with only one -- a broken-ribbed Ben Tate -- running back that day.

So while it's great Foster's body has healed, the real tests for him will come later. They'll come when practices begin, and when, more importantly, games begin and Foster deals with the grueling nature of his position.
