49ers sign quarterback Josh Johnson to a two-year deal

According to ESPN’s Josina Anderson, the San Francisco 49ers have signed back up quarterback Josh Johnson to a two-year deal.

Johnson will reunite with 49ers head coach Jim Harbaugh who coached him at the University of San Diego.

Johnson will serve as a back up to Alex Smith.  He has the mobility to run and throw and he’s very similar to Robert Griffin III, but not as talented.
