Jackson's spike sets off confusion   

SAN DIEGO (AP) -- A moment of celebration by San Diego receiver Vincent Jackson turned into 10 minutes of confusion in the fourth quarter of the Chargers game with the rival Oakland Raiders.

With the Chargers trailing 14-7 and facing fourth-and-2 from the Raiders 40, Jackson caught a 13-yard pass from Philip Rivers, rolled to the ground untouched, then stood up and spun the ball forward. Oakland's Fabian Washington jumped on the ball, believing it was a fumble, and setting off 10 minutes of confusion as the referees sorted it out.

Referee Mike Carey originally signaled Oakland's possession, but then the Chargers were flagged for illegal forward pass. Even with the 5-yard penalty for the illegal pass, the Chargers still had a first down, at the 32.

Four plays later, LaDainian Tomlinson threw a 19-yard touchdown pass to Antonio Gates to tie the game at 14.
