Chargers' Merriman leaves game with left knee injury
The quarterback limped off the field after taking a blow from defensive end Antwan Odom in the second quarter.
Rivers handed the ball to LaDainian Tomlinson, rolled out and was clipped to the ground. He tried to walk off the field, nearly falling on his way to the sideline.
Rivers headed to the locker room, and was replaced by Billy Volek. But he was back for San Diego's opening series of the third quarter.
Chargers linebacker Shawne Merriman left the game in the second quarter with a left knee injury. Merriman already had two sacks in the game, tying his season high from last week. He was listed as questionable to return.
San Diego added to its slew of injuries when fullback Lorenzo Neal was carted off the field for X-rays on his right leg in the fourth quarter.
Titans offensive lineman Jacob Bell also left with a "burner." He was wearing street clothes on the sideline in the second half, and did not return.
