Two years ago, longtime 49ers running back Frank Gore opted to sign with the Indianapolis Colts in free agency. Since then, no player has worn the No. 21, likely out of respect for the 49ers great.
As much as the team seemingly wants to give that number away, it will probably go unworn again in 2017. Tim Hightower, San Francisco’s newest running back, was assigned Gore’s old number, but he took to Instagram to announce he won’t be wearing it.
