SANTA CLARA — Frank Gore won't be playing in Sunday's Pro Bowl because of an injury, and although the 49ers haven't specified its nature, word surfaced Monday night that he may have broken a hand in the NFC Championship game loss at Seattle.
Gore held an autograph signing in Burlingame at Lefty's Sports shop, which posted news on its social-media forums that Gore played Sunday through his hand injury that may require surgery Tuesday.
Neither the 49ers nor Gore's agent could be immediately reached for confirmation. Coach Jim Harbaugh will address the media Tuesday at noon in his season-closing news conference.
Gore matched his season-low with 14 yards on 11 carries in the 23-17 defeat to the Seahawks. He had a 17-yard catch on fourth down to extend the 49ers' final series, which ended in a Kaepernick pass getting intercepted in the end zone.
Gore, 30, is the 49ers' all-time rushing leader, and the ninth-year veteran ran for 1,128 yards and nine touchdowns this regular season. He appeared in all 19 games, and he is under contract through 2014 with a base salary of $3.3 million.
The Dallas Cowboys' DeMarco Murray was assigned Gore's Pro Bowl spot Monday. The 49ers had eight players selected to the NFL's all-star game, but only linebacker Ahmad Brooks is expected to attend. The 49ers' other honorees are bypassing it because of injuries, including linebackers NaVorro Bowman and Patrick Willis, guard Mike Iupati, tight end Vernon Davis, defensive tackle Justin Smith and left tackle Joe Staley.
