It is an apparent right shoulder injury for Hunter that is being investigated. Hunter left the game in the second quarter with three catches for 26 yards.

The Buffaloes trail Kansas State 14-7 at halftime.

Hunter (who was not on the field for the first defensive play of the second half) and fellow Colorado receiver Jimmy Horn Jr. are both doubtful to return in the second half.

This story will be updated as more is known about their status.
