Jefferson (undisclosed) reverted to the Vikings' injured reserve Monday, per the NFL's transaction log.
Jefferson had a solid preseason, rushing 11 times for 74 yards over three contests. The running back was waived Sunday and cleared waivers, meaning he is set to spend the entirety of the 2026 regular season on IR. If Jefferson would like to sign with another team, he will need to reach an injury settlement with the Vikings to become a free agent.
