Here is the official release from the Browns regarding QB Colt McCoy-
“The Cleveland Browns today acquired two undisclosed 2013 draft choices from the San Francisco 49ers in exchange for quarterback Colt McCoy and an undisclosed 2013 pick. The Browns now own seven picks in the 2013 NFL Draft, which will be held April 25-27.
McCoy was a third-round pick by the Browns in 2010 and started 21 of his 24 career games. He completed 409 of 702 career passes for 4,388 yards with 21 touchdowns and 20 interceptions. He registered a 6-15 record as a starter.”
Those undisclosed picks were quickly disseminated–
“The Browns sent the 25-year-old quarterback along with a sixth-round draft pick to the Niners for a fifth- and seventh-round selections, The Plain Dealer confirmed this afternoon.”
So the Browns sent McCoy and their sixth round pick (173 overall) to San Fransisco for a fifth round pick (either #157 or #164 overall) and a seventh round pick (227 overall).
