The Indianapolis Colts will be without one of their top offensive weapons after running back Marlon Mack suffered a fractured hand in the Week 11 win against the Jacksonville Jaguars.

Mack underwent a procedure on Monday morning and while there isn’t a specific timetable for his return, the third-year back is expected to miss some time.

However, it doesn’t appear to be long enough to have a discussion of putting Mack on the injured reserve list.

“That has not been discussed at this point,” head coach Frank Reich told reporters Tuesday.

The Colts will be without Mack for a crucial part of the schedule—one that likely determines the fate of their season. They have the short week against Houston, then they are at home against the Tennessee Titans before two road trips against the Tampa Bay Buccaneers and the New Orleans Saints.

Mack has been enjoying a Pro Bowl-caliber season. Entering Week 12, he has taken 192 carries for 862 yards and four touchdowns while averaging 4.5 yards per carry. He’s currently fifth in the NFL in rushing yards.

The 23-year-old will be out a few weeks to recover from the injury, but as Adam Schefter reported on Monday, it’s not believed to be season-ending.
