The expected bad news came down for Indianapolis Colts RB Marlon Mack.
NFL Network's Tom Pelissero reported that an MRI confirmed the RB tore his Achilles, per a source informed of the situation. The injury will end his season.
The test verified there was little hope for good news for Mack and the Colts after he left Sunday's loss against the Jacksonville Jaguars in the second quarter. Colts coach Frank Reich later confirmed the diagnosis.
"Marlon is beloved in this locker room," Reich told reporters. "... He was looking so good in training camp, and even in his snaps yesterday. He looked like lightning. It was very bad timing for him and his family."
Mack earned four carries for 26 yards and three catches for 30 before leaving with the injury. The starting running back is coming off a 2019 campaign in which he rushed for 1,091 yards. In four years, the RB has never played a full 16-game slate. He'll make it just one tilt in 2020.
Mack is set to be a free agent in 2021. The injury could spell the end to his run in Indy.
Sans the starter, Nyheim Hines and rookie Jonathan Taylor each had 15 touches, with Taylor earning 89 scrimmage yards and Nines 73 scrimmage yards and two TDs (1 rush, 1 receiving) while getting much of the red-zone work.
