The Denver Broncos signed running back Marlon Mack to the active roster from the San Francisco 49ers' practice squad.
Mack traveled with the Broncos to London for their Week 8 matchup against the Jacksonville Jaguars. He will replace Mike Boone (ankle) as the No. 3 running back behind Melvin Gordon and Latavius Murray for at least the next four games while Boone is on injured reserve. Mack might sprinkle in for a few touches, but barring fumbling issues or an injury, most of the Broncos' backfield work will go to Gordon and Murray.
numberFire's models project Mack for 3.3 touches and 15.8 yards in London. He appeared in six games for the Indianapolis Colts last season and rushed 28 times for 101 scoreless yards. The Jaguars are allowing the sixth-most FanDuel points per game to the running back position this season and their run defense is No. 17 in our adjusted team metrics.
