Johnson was listed as a non-participant in Wednesday's walk-through practice due to a quadriceps injury.

EDGE Analysis

Head coach David Culley relayed earlier Wednesday that Johnson picked up the injury during the Texans' Week 15 win over the Jaguars. Johnson now has two more chances to get on the practice field prior to Sunday's game against the Chargers, but even if he gets the green light to play, he could be part of a timeshare out of the backfield with Rex Burkhead.
