FILE - In this Nov. 19, 2012 file photo, San Francisco 49ers quarterback Alex Smith, left, talks with former quarterback and NFL broadcaster Steve Young before an NFL football game against the Chicago Bears in San Francisco. A person with knowledge of the trade tells The Associated Press that the Kansas City Chiefs have agreed to acquire Smith from San Francisco. The person spoke on condition of anonymity on Wednesday, Feb. 27, 2013, because the trade does not become official until March 12, when the NFL's new business year begins.
