Colt McCoy, traded by the Cleveland Browns, is eager to get started with the San Francisco 49ers.

The trade was finalized after the quarterback passed a physical on Tuesday.

"I actually showed up in Cleveland yesterday to start the offseason," McCoy said. "I didn't really know what was going to happen. I think there was a lot of speculation. At the end of the day yesterday I was a 49er, and I couldn't be more happy."

McCoy will have the chance to win the backup job behind Colin Kaepernick.
