Patterson signed with the Chargers' practice squad Monday, per the NFL's transaction log.
Patterson was let go by the Bolts in late August after failing to make the team's initial 53-man roster, but he's now found a spot on the practice squad. The 24-year-old running back's last regular-season action came in 2022 with the Commanders, when he appeared in three games and recorded 78 rushing yards on 17 attempts.
