"The Cardinals plan to open contract discussions soon with the agent for defensive end Calais Campbell, said General Manager Rod Graves.

Graves said the Cardinals are entering a period where they will discuss extensions for players. "He (Campbell) is certainly one of the guys we'll be talking about," Graves said.

Campbell is in the final year of his rookie contract and is due to be an unrestricted free agent in 2011. He leads the Cardinals in sacks with five and has blocked two field goals this season."
