The San Francisco 49ers are involved in talks to trade quarterback Alex Smith and believe they're going to be able to make a deal, league sources say.
The earliest San Francisco can complete a trade of Smith is on March 12 after 4 p.m. ET, which is when the 2013 league year officially begins.
San Francisco has found a legitimate amount of interest, according to sources. The Kansas City Chiefs are interested and the Arizona Cardinals also are thought to be.
There is no deal in place right now, sources said.
