With Colin Kaepernick ailing and Thad Lewis done for the season, the 49ers have added a veteran to the quarterback room.
Christian Ponder has signed a one-year deal with San Francisco. Ponder takes the 90-man roster spot the 49ers opened up by putting Lewis on injured reserve.
Ponder has been out of the NFL since the Broncos cut him in December. Before that he spent some time with the Raiders. Ponder started 36 games in four seasons with the Vikings, who drafted him in the first round in 2011.
In addition to Ponder, the healthy quarterbacks in San Francisco are starter Blaine Gabbert and rookie sixth-round draft pick Jeff Driskel.
