The 49ers are giving Daunte Culpepper a shot to return to the NFL. Culpepper will visit with and work out for San Francisco this week, according to a league source. 49ers coach John Harbaugh suggested that he'd consider adding a veteran quarterback to compete with Alex Smith and rookie Colin Kaepernick. Culpepper, the 11th overall pick in the 1999 draft, has played for the Vikings, Dolphins, Raiders, and Lions.
