Houston Texans wide receiver Andre Johnson underwent surgery on his injured hamstring, and while the Texans have yet to stray from their three-week recovery projection, it is as of yet unknown if this timetable is indeed correct.
The report, from Houston Chronicle reporter Stephanie Stradley, says that the type of surgery he underwent—to reduce pain and prevent scar tissue from building up—is consistent with a short recovery time. Therefore, the three-week projection shouldn't be too far from the truth.
Johnson's fantasy owners shouldn't overreact at the news of his surgery. Whether he misses just three weeks or a few more than that, he will return. There's zero chance of his starting gig being grabbed out from under him by Jacoby Jones, while there's a 100 percent chance of Johnson returning to the dominant form that made you draft him in the first place, once he is healed.
Unless you're suffering from a severe lack of depth at another position, I'd keep him on your roster while he recovers. Considering he won't be of use to you or any other fantasy GM in your league for a few weeks, he's obviously not a sell-high. If you're looking to try to trade him straight-up for running back Fred Jackson, for example, this is probably not the right time.
He's worth more to your team, even on the bench, than any value you can get for him through a trade right now. Try to shore up your wide receiver depth and hope for the best while he's out.
Once he returns, he will pick up where he left off as one of the highest-scoring fantasy receivers of the year.
