Marlon Mack suffered a season-ending torn Achilles during the Indianapolis Colts' Week 1 loss to the Jacksonville Jaguars.

Mack suffered the injury after catching an underneath pass in the second quarter. He immediately grabbed his ankle, got up and took off his helmet before waving for assistance from the Colts' sideline.

Mack is in the final season of his contract as the Colts didn't offer him an extension in the offseason.
