According to Jason La Canfora of CBS Sports, the San Francisco 49ers have expressed that a deal to trade quarterback Alex Smith is already done and will be finalized once free agency begins. There has been much speculation recently that the Kansas City Chiefs are very interested in the 49ers quarterback.

@JasonLaCanfora:
The 49ers have expressed to others that a deal for QB Alex Smith is effectively complete. Can't be finalized til league year begins 3/12 so it's not official, both clubs view it at as it's effectively done. I do not know the other team. KC and JAX are 2 teams that make sense

Ryan O'Halloran of the Florida Times-Union says that, according to GM Dave Caldwell, it is not the Jacksonville Jaguars that have a deal in place for Smith.

@ryanohalloran:
#jaguars GM Dave Caldwell says via text "not us" who has deal in place for SF QB Alex Smith.

Mary Kay Cabot, a beat writer for the Plain Dealer Brown, says that the team that has a deal in place with the 49ers is not the Cleveland Browns, so scratch them off the list as well.
