Vikings running back Adrian Peterson was mostly back on the sidelines Tuesday.
Peterson, recovering from a right thigh bruise, sat out practice with the exception of doing some late light work without a helmet. He was hurt Aug. 11 in practice and missed workouts for two days before returning to limited duty on Monday.
Peterson won't play in the exhibition season. He's expected to next take the field Sept. 14 in the regular-season opener at San Francisco.
Sitting out all of practice were tight end MyCole Pruitt (sprained left ankle), defensive tackle Shamar Stephen (knee), safety Antone Exum (undisclosed injury), tackle Carter Bykowski (shoulder) and cornerback Josh Robinson (torn labrum), who remains on the physically unable to perform list.
