The San Francisco 49ers have agreed to trade quarterback Alex Smith to the Kansas City Chiefs, league sources confirmed to ESPN. Kansas City will trade its second-round pick in the 2013 draft -- the second selection (No. 34 overall) in the round -- as well as another conditional mid-round pick in 2014 to acquire Smith from San Francisco, a league source told ESPN. The 49ers now own 15 picks in the 2013 draft.
