The Indianapolis Colts had a tough opening game, falling to Jacksonville 27-20 and also losing starting running back Marlon Mack in the first half with a right Achilles tendon injury.

Mack caught a 3-yard pass at the Colts’ 48 midway through the second quarter and immediately went down before grabbing at his foot. The injury was initially described as an ankle injury before coach Frank Reich said after the game that it was Mack’s Achilles tendon.

“He will get a scan tomorrow,” Reich said. “That’s all we know for right now.”

Mack topped the 1,000-yard mark for the first time last season and is in the final year of his rookie contract. Losing him would be a huge blow, although Indy drafted Wisconsin star Jonathan Taylor in the second round of the draft this year.
