Lakers' center Andrew Bynum claims that he isn't concerned about a possible contract extension with the team.

"It's not a concern of mine at all," Bynum said. "That's business. My agent takes care of it. What I've got to do is play well and make people believe that I'm the great player I'm supposed to be."

Bynum and the Lakers have until Oct. 31 to come to an agreement.

He averaged 13.1 points, 10.2 rebounds, and 2.1 blocked shots last season before he suffered a season-ending knee injury in January.
