Alex Smith is headed to Kansas City, the first major acquisition by the Chiefs since Andy Reid took over as head coach.
A person with knowledge of the trade told The Associated Press on Wednesday that the Chiefs have agreed to deal for the 2005 top overall draft pick who lost his starting quarterback job in San Francisco to Colin Kaepernick last season.
The trade will not become official until March 12, when the NFL's new business year begins.
Another person familiar with the deal said the 49ers will get a second-round draft pick in April, No. 34 overall, and a conditional pick in the 2014 draft.
Smith, 28, struggled for most of his career in San Francisco, plagued as much by coaching and coordinator changes as by his own indecisiveness. But when Jim Harbaugh became coach, Smith blossomed. He was among the league leaders in passer rating (104.1) with a 70.2 completion percentage when he suffered a concussion in a 24-24 tie against Nov. 11 against the Rams.
Smith never started again for the 49ers, but now will replace Matt Cassel in Kansas City.

Kasa told ESPN Radio in Denver that during interviews with team officials at the combine in Indianapolis: "(Teams) ask you, like, 'Do you have a girlfriend?' 'Are you married?' 'Do you like girls?' "
