Rivers fined $7,500 for taunting

The NFL fined San Diego quarterback Philip Rivers $7,500 for taunting in San Diego's 24-20 comeback win over Oakland, an NFL spokesman said.

Rivers threw the ball at the ground, took his mouthpiece out and said something in the direction of Oakland defensive tackle Gerard Warren during the third quarter on Monday night. He was penalized 15 yards.

After the game, Rivers denied that he was taunting Warren.

Rivers led two Chargers touchdown drives, including an 89-yard drive for the winning score in the final seconds.
