Chargers running back LaDainian Tomlinson came out of Sunday's night game against Oakland with a rib injury, but returned for the start of the second half. The extent of the injury wasn't immediately known. Tomlinson jogged to the locker room, accompanied by a team doctor, with 22 seconds left before halftime. A few seconds later, his backup, Michael Turner, scored on a 2-yard run to give San Diego a 17-10 lead. Tomlinson apparently was hurt on a 3-yard run late in the second quarter. He came off the field, took off his helmet and began speaking with the team's medical staff. Tomlinson carried on San Diego's first two plays from scrimmage in the third quarter.
