Broncos RB Marlon Mack hurt his hamstring in the 1st quarter of Sunday's game vs. the Chiefs and is questionable to return. His absence leaves Denver's backfield to Latavius Murray and Chase Edmonds.

Cardinals RB Marlon Mack has torn his left Achilles' tendon and will miss the season. It's his second time dealing with such an injury. Mack tore the right Achilles' in Week 1 of 2020. The latest injury seems likely to end the 27-year-old's NFL career. He has logged just 44 total carries since the 2020 tear. Don't be surprised if the Cardinals look to bring in another veteran RB.

The Cardinals signed RB Marlon Mack. Since tearing his Achilles in September of 2020, Mack has totaled just 185 yards on 44 carries. Arizona has only RBs Keaontay Ingram, Corey Clement, and Ty'Son Williams behind James Conner, but Mack still isn't guaranteed a roster spot. He's not worth a roster spot in fantasy football.

Broncos RB Marlon Mack will miss Sunday's finale vs. the Chargers with the hamstring injury he suffered in Week 17, according to insider Mike Klis. That'll leave Denver's backfield to Latavius Murray and Chase Edmonds. Murray tallied 12 carries and 6 targets to Edmonds' 7 carries and 3 targets in last week's loss to the Chiefs.

The Broncos are signing RB Marlon Mack off the 49ers' practice squad. Per 9News' Mike Klis, the team hopes to get Mack to Denver in time for this afternoon's flight to London. The move suggests that RB Mike Boone will miss at least Sunday's game vs. Jacksonville with his ankle injury. Don't expect Mack to see much action, though, behind RBs Melvin Gordon and Latavius Murray.

The 49ers have promoted RB Marlon Mack from the practice squad. San Francisco has already lost RBs Elijah Mitchell and Ty Davis-Price to multi-week injuries. Jeff Wilson will open Week 3's game vs. the Broncos as the lead back, with Mack and rookie Jordan Mason behind him. Mack hasn't looked like the same player since his 2020 Achilles tear, so we're not optimistic about his chances of making an impact with the 'Niners. He's only worth stashing in deep fantasy leagues.
