SANTA CLARA, Calif. (AP) — The San Francisco 49ers have added another quarterback to the competition to be Colin Kaepernick’s backup, signing nine-year veteran and former Iowa State star Seneca Wallace to a one-year contract Thursday.

While Colt McCoy had appeared to be the favorite to win the No. 2 job coming into training camp, neither he nor Scott Tolzien have separated themselves. Even rookie B.J. Daniels has been deemed a contender, though clearly Wallace now will get a chance with little time to prepare before the Sept. 8 season opener against Green Bay.

Wallace, who was competing with Luke McCown to back up Drew Brees in New Orleans, had his contract terminated by the Saints on Monday.

San Francisco waived wideout Ricardo Lockette, who worked out with Kaepernick in Atlanta for a stretch this offseason along with departed A.J. Jenkins.
