The Chargers downgraded Melvin Gordon (hamstring) to questionable Saturday and promoted undrafted rookie Detrez Newsome from the practice squad.
Gordon missed part of the team's practice Friday after injuring himself but came back and, therefore, was taken off the injury report. But he returned a day later, the addition of Newsome an indication that the Chargers are concerned about Gordon's availability.
If Gordon is unable to play against Tennessee, Austin Ekeler would move into a more prominent role. Rookie Justin Jackson also could be used more.
Gordon has emerged through six games as one of the team's most versatile weapons. He leads the Chargers with 466 rushing yards and has scored all six of their touchdowns on the ground. Three of those scores came last week against Cleveland. He is second on the team with 30 receptions for another 279 yards.
