SANTA CLARA, Calif. (AP) The agent for Pierre Thomas says the running back is joining the San Francisco 49ers, desperate at the position given a rash of injuries.

C. Lamont Smith posted Tuesday on Twitter that his client was coming to the Bay Area, though the team had yet to make an announcement during a wild two-day stretch of change.

The 49ers (2-6) traded tight end Vernon Davis to Denver on Monday and also are benching struggling quarterback Colin Kaepernick in favor of backup Blaine Gabbert for Sunday's game against Atlanta, a person with knowledge of the decision said late Monday. The offense has gone two straight games without a touchdown.
