Yeldon sat out his fourth consecutive practice Wednesday because of a groin injury. The rookie missed all three workouts last week and did not play in a loss to Houston. Without him, Toby Gerhart and Denard Robinson combined for 45 yards on 16 carries.
Yeldon has 291 yards rushing, 73 yards receiving and a touchdown this season.
Running back Bernard Pierce returned to practice after spending last week in the NFL's concussion protocol.
