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.

The San Francisco 49ers are nearing agreement on a trade of Alex Smith.

The identity of the team is not yet clear, but it is believed to be the Kansas City Chiefs.

NFL.com's Ian Rapoport reported on the NFL Network that the Chiefs have the most interest in Smith.

An actual agreement can't become official until Mar. 12.

The Kansas City Chiefs are interested in keeping Dwayne Bowe.

Bowe accepted the Chiefs' one-year, $9.5 million offer last summer.

Bowe and the Chiefs are discussing a new deal.

The Kansas City Chiefs are interested in trading for Nick Foles if he becomes available.

Andy Reid became head coach of the Chiefs this offseason and wants to add a quarterback.

Former NFL scout Daniel Jeremiah, now an NFL.com analyst, reported Reid and Chiefs offensive coordinator Doug Pederson, an assistant coach with the Eagles under Reid, "were very high on Nick Foles and his future."

The Chiefs own the No. 1 overall pick but are unlikely to use it on a quarterback.

Alex Smith is also a possibility for the Chiefs.

Chris Canty is expected to decide between the Kansas City Chiefs and Tennessee Titans.

Canty was cut this offseason by the New York Giants.

Canty had three sacks and 26 tackles over nine games in 2012.

The San Francisco 49ers will attempt to find a trade for Alex Smith, according to sources.

Both the Cleveland Browns and Kansas City Chiefs are rumored to be interested in Smith.

f San Francisco deals him instead of cutting him it would save the $1 million or $2 million roster bonus it would have to pay if he is released.
