TITANS 17While LaDainian Tomlinson was as tough as ever, Drew Brees played as if he had something to prove.

Brees, who's had a tenuous grip on his job since last season, threw for three touchdowns Sunday, including a 58-yarder to Reche Caldwell midway through the fourth quarter, and Tomlinson rushed for 147 yards and one touchdown to lead the Chargers to a 38-17 win over the Tennessee Titans.

The Titans (1-3) played without quarterback Steve McNair, who was the emergency third quarterback after bruising his sternum in a loss to Jacksonville last week. Billy Volek threw for 278 yards and two scores, but it wasn't enough to keep the Titans from their third straight loss.

Brees's big game came six days after rookie Philip Rivers was promoted from third-stringer to backup quarterback. The Chargers (2-2) didn't need to call on Rivers, especially after Brees and Caldwell helped put away the Titans in the fourth quarter and snap a two-game losing streak.

Tomlinson, who carried 17 times, became the Chargers' all-time leading rusher with 4,979 yards in four seasons, breaking the mark of 4,972 yards held by Paul Lowe, who played with San Diego from 1960 to '68. Brees was 16 of 20 for 206 yards.

LaDainian Tomlinson is far out of the reach of the Titans' Antwan Odom on 15-yard touchdown run.
