Gore had his socks at ankle level against the Falcons on Sunday. He had red legwarmers on, which slid down to his ankles during the game. The NFL has a policy where socks need to be pulled up to the knee level.
This is the second time Gore has been fined this year. He and Michael Crabtree were previously fined $10,500 for throwing a ball into the crowd against the Arizona Cardinals in the regular season finale.
Gore finished the NFC Championship game with 90 rushing yards and two touchdowns against the Falcons.
