San Francisco closed its preseason with a 30-23 win over Los Angeles, resting most starters but still evaluating depth as roster cuts loom. Nick Martin anchored the middle with eight tackles, a tackle-for-loss and a forced fumble that sparked SF’s second score, plus a standout fourth-quarter stop on special teams. Demarcus Robinson provided a veteran presence with two catches for 30 yards, including a 22-yard TD, while Jeff Wilson led SF’s backups with 41 rushing yards and a score. Tanner Mordecai steered the reserve unit, and Thomas Morstead logged seven punts for 314 yards, flipping field position multiple times. Curtis Robinson’s return of a DJ Uiagalelei turnover and a disruptive edge presence from Robert Beal and Trevis Gipson capped strong depth-showing for the Niners.
