SAN DIEGO -- The 49ers, who had five quarterbacks on their roster three days ago, are down to the three who figure to open the regular season on their 53-man roster.

Veteran Seneca Wallace was not on the field for warmups prior to the 49ers' exhibition final against the San Diego Chargers. Colin Kaepernick, Colt McCoy and B.J. Daniels took part during pregame drills.
Wallace did not make the trip to San Diego after informing coach Jim Harbaugh earlier in the day that he planned to not continue to attempt to play football, Harbaugh said after the game. Wallace, who was likely to be cut, is a seven-year veteran. He did not play in the NFL last season after the Cleveland Browns released him during training camp.
Wallace, 33, spent his first seven seasons with the Seahawks. He did not play his first two years and started 14 games over the five seasons in Seattle. He moved onto Cleveland, where he started seven games as Colt McCoy's backup in 2010 and 2011.
The 49ers signed Wallace one week ago. He saw limited action in the team's exhibition game Sunday night, and completed both pass attempts for 27 yards.
On Monday, the 49ers released Scott Tolzien, who served the past two seasons as the team's No. 3 quarterback.
