Wide receiver Torrey Smith is poised to leave the Ravens as a free agent, according to multiple NFL sources, and the San Francisco 49ers are the front-runners to land the former Maryland standout.

For Smith to have remained with the Ravens, which several league sources reiterated has been an extremely unlikely scenario for weeks, he would have had to leave several million dollars on the table.

Although no deal has been finalized, sources indicated there's strong mutual interest between the former University of Maryland standout and San Francisco. Deals cannot become official until Tuesday at 4 p.m. when the league year begins.

There are several connections between the 49ers and Smith, including former Ravens wide receiver Anquan Boldin and former Maryland tight end Vernon Davis. Smith has maintained a strong friendship with Boldin since he was traded to the 49ers for a sixth-round draft pick following the Ravens' Super Bowl XLVII victory.
