A former University of Colorado football player has pleaded guilty to assaulting a Boulder police officer who responded to a report of a domestic disturbance.

The Daily Camera reports 23-year-old Nathaniel Robbins pleaded guilty Friday to felony assault on a peace officer along with two counts of misdemeanor assault, felony trespassing and violating a protection order.

Police say Robbins tackled one of two officers that responded to a domestic disturbance in March 2016, causing both officers to fall down a flight of stairs. Robbins was arrested again in October after police found him at the residence of his former girlfriend. A neighbor reported Robbins forced his way into the residence.

Sentencing is set for May 19. He remained jailed Sunday.

Robbins played in four games for the Buffs in 2015.
