There were a lot of questions for coach Jim Harbaugh on Monday, the day after the 49ers' 21-19 loss to the Arizona Cardinals.
Harbaugh was short on answers, but he disclosed running back Frank Gore is banged-up.
Gore's health was the reason he carried just 10 times for 72 yards on Sunday. Gore has not missed a game, but he has played through two ankle sprains this season. Gore has been the workhorse for the team with 234 rushing attempts this season for 1,054 yards. He also has 16 receptions.
"He's got some things," Harbaugh said. "He's not 100 percent. And we have other backs who got carries in the second half."
