Word on how long Andre Johnson’s injury will keep him out of the Houston Texans’ lineup has been hard to come by. So we’re grasping to every morsel of information that slips out regarding the world’s most talked about hamstring.

Today, ESPN’s John Clayton reported/predicted/guessed that Johnson is “definitely gonna miss the Raiders game and probably two or three weeks after that,” according to Evan Silva of NBC Sports.

Clayton went on to say that Johnson would probably miss three weeks.

Yesterday, Texans head coach Gary Kubiak wasn’t sure if Johnson would be out a few days or a few weeks, but Johnson is apparently going for second and third opinions on the injured hammy, which isn’t a good sign.

A hamstring isn’t something that a player like Johnson can rush back from, so we’re not expecting him to be back until late October. That’s a guess, of course. But at this point, we’re not sure whether Clayton is relaying gut feelings or making predictions based on what he’s hearing.

The running game is strong and the defense might be good enough to get them through a short stint without their best player. The Texans went 2-1 without Johnson in the lineup last season.

Life without Johnson in 2011 (probably) starts Sunday against Oakland. Last year, the Texans beat the Raiders in Oakland without Johnson’s services. This year, the running game is just as strong, and Owen Daniels is healthier and playing well.

So they might survive against the Raiders at home, but it gets a lot more tricky in Weeks 6 and 7, when Houston has to travel to Baltimore and Tennessee to face the league’s top two scoring defenses. The Ravens and Titans are a combined 6-2 and have surrendered an average of only 14.1 points per game thus far.
