Domata Peko has described Philip Rivers as "a real competitor" ahead of the Cincinnati Bengals' playoff game against the San Diego Chargers this weekend.

The Chargers quarterback has returned to form in 2013, completing 4,478 passing yards and 32 touchdown passes to guide the AFC West side to a wildcard spot in the post-season.

The Bengals defensive tackle told reporters: "He's been having a hell of a year. He's been really accurate with the ball. They are number one in the league on third down. That's going to be one of the keys to the game. They are almost 50% on third down.

"Philip Rivers has been playing for a long time. He knows where players are going to be. He gets the ball out quick. He can sling that thing deep. He's a real competitor. We can't wait to get after him.

"It all starts up front. We have to start by stopping the run. After we establish we are stopping the run, we can get after him, and get in his face."

The Chargers face the Bengals at the Paul Brown Stadium on Sunday.
