The 49ers signed Wallace on August 22. If true, this would leave Colt McCoy and B.J. Daniels as the team's backup quarterbacks behind Colin Kaepernick for the season. On Monday, the 49ers released quarterback Scott Tolzien.
Matt Maiocco of CSN Bay Area is reporting that Wallace did not make the trip to San Diego "for personal reasons."
