Colts’ RB Marlon Mack is undergoing surgery on his fractured right hand today and is out indefinitely, per source. It is not thought to be season-ending at this time, however.— Adam Schefter (@AdamSchefter) November 18, 2019
Mack was on his way to his best game of the season Sunday before leaving with the injury. Jonathan Williams stepped in and immediately produced against a bad Jaguars run defense. He seems to have the inside track to the starting job in Indy and should be 100% rostered if you need a running back.
