The Kansas City Chiefs have agreed to trade for Alex Smith with the San Francisco 49ers.

The deal cannot become official until Mar. 12.

The 49ers will get a No. 2 pick in this year's draft and a similar pick in 2014, according to a source that spoke with Tim Kawakami of the Mercury News.

Smith lost his job as starting quarterback of the 49ers to Colin Kaepernick following a concussion. Kaepernick quickly ended the controversy with several signature performances and eventually led the 49ers to an appearance in the Super Bowl.

With this bold trade, Andy Reid is clearly gambling his success with the Chiefs on the performance of Smith.

The Browns, Cardinals and Jaguars were the other teams believed to be interested in trading for Smith.
