Seneca Wallace is retiring from football. It was apparently Wallace's call not to suit up in Thursday's preseason finale. "He felt strongly about it," coach Jim Harbaugh said. "I don't talk people out of that. I've never seen it done on game day, but I wish him well." A 2003 fourth-rounder, Wallace hangs it up with a career 81.3 QB rating, 59.2 completion percentage and 31:18 TD:INT ratio through 764 passes. Wallace hasn't played since 2011.
