Chris Johnson -- 1st Pic After Being Shot ... With Warning to Gunman

Sporting a sling on his injured arm, NFL running back Chris Johnson posed for a photo for the first time since he was shot in the shoulder during a drive by shooting in Florida this weekend.
Johnson appears in the photo with two other men -- one of whom is sporting bandages on an injured arm ... and the other who is flipping off the camera.
The man with the double-bird is rapper Kenny Turner -- a friend of Johnson's who posted the pic and included a message that appears to be directed at the shooter.
