Former Buc QB Josh Johsnon will be reuniting with his former college coach, Jim Harbaugh, for the 2012 NFL season as Johnson has just signed a two-year deal with the San Francisco 49ers.

Johnson played for Harbaugh at the University of San Diego where he set the NCAA Football Championship Subdivision record for passing efficiency. Johnson played his first four seasons in the NFL with the Tampa Bay Buccaneers and will now reunite with Harbaugh in San Francisco.

The 49ers still have Alex Smith on the team so it isn’t clear what role Johnson will have on the time.

Niners general manager Trent Baalke, said: “Josh is a promising young player that has experience in our offensive system. He is a skilled athlete with good arm talent. Josh has shown promise in limited action, both as a backup and starter at the NFL level. We are pleased to add him to our team.”
