Kubiak said Johnson currently is following the NFL concussion protocol. The coach also said the star wide receiver "did great" Monday, according to the Texans' official website, and was able to ride a stationary bike. Kubiak added that Johnson's availability for Week 3 should be an "end-of-the-week decision."
Johnson was injured late in the fourth quarter Sunday on a key 21-yard reception during Houston's game-tying touchdown drive. Johnson came down hard on the sideline, hitting the back of his head against the turf, then exited the game and didn't return.
