Any time a No. 1 overall pick appears anything other than 100 percent, there’s going to be concern.

But for Texans pass-rusher Jadeveon Clowney, his history is going to cause people to notice even the slightest limp.

According to Tania Ganguli of ESPN.com, Clowney was wearing a walking boot on his right foot Friday.

He left Thursday’s game against the Colts briefly, but returned to finish the game, playing more than half the snaps.

Of course, Clowney missed most of his rookie year with knee problems, and is coming back from microfracture surgery anyway.

The boot might not be a sign of serious injury, but with Clowney, it’s worth keeping an eye on.
