Houston's offensive line is shaping up as one of the biggest questions marks among NFL position groups this year.
Third-round rookie Martinas Rankin is recovering from surgery to repair a foot injury sustained in last month's rookie minicamp.
"He's doing well," coach Bill O'Brien said Tuesday, via the Houston Chronicle. "He's a smart guy. I think he's picked up the things we've taught him. He's picked them up well and I think he has a good future here. We'll see how it goes."
Although Rankin is expected to return in time for the start of the regular season, his availability for training camp is less certain.
If Rankin is a realistic candidate to start in Week 1, he can't afford to miss valuable practice reps as O'Brien installs a new offense that plays to Watson's strengths.
