With two-time NFL rushing champion LaDainian Tomlinson bottled up by the Titans defense and three-time All-Pro tight end Antonio Gates lost to a sprained left big toe late in the second quarter, quarterback Philip Rivers stepped up, throwing a 25-yard touchdown pass to Vincent Jackson late in the third quarter that gave San Diego its first lead at 10-6. Rivers was 19-of-30 for 292 yards, with one interception.
