The Green Bay Packers signed quarterback Seneca Wallace, who is expected to serve as Aaron Rodgers' backup for the team's regular-season opener at San Francisco on Sunday.
Wallace left the 49ers last Thursday after spending one week with the team, although coach Jim Harbaugh did not confirm reports that Wallace told the team he intended to retire. What was clear was Wallace was not going to unseat Colt McCoy as Colin Kaepernick's backup in San Francisco.
The Packers released Vince Young on Saturday after hoping he would serve as a veteran backup. General manager Ted Thompson said he should have brought in Young sooner and gave him more time to learn the offense.
"Quite frankly, it probably wasn't fair to Vince," Thompson said. "We threw a lot on his plate, and the fault is probably mine. I probably should have had him in here earlier."
B.J. Coleman was released to create a roster spot for Wallace.
With the signing of Wallace, the Packers now have two quarterbacks who have insight into the 49ers' offense. Scott Tolzien, who is on Green Bay's practice squad, was the 49ers' No. 3 quarterback the past two seasons before being released last month.
Packers coach Mike McCarthy said in February that he still thinks "every day" about 49ers quarterback Colin Kaepernick gouging the defense. Green Bay invested in and researched defending the spread-option -- the offense run by the 49ers -- including sending defensive coaches to meet with Texas A&M coach Kevin Sumlin.
--Along with Tolzien the Packers signed five more players to their practice squad: G Bryan Collins, WR Charles Johnson, CB James Nixon, TE Jake Stoneburner and WR Myles White.
