LINCOLN — Upon further review, Nebraska isn't so sure the play that caused Adrian Martinez's knee injury was entirely clean.
Colorado was not penalized following the fourth-quarter play, a one-yard Martinez run to the right that was negated by holding. But video — the best available shot comes from KLKN in Lincoln — shows 230-pound CU linebacker Jacob Callier grabbing Martinez's right shin and pushing his ankle into the turf as other defenders tackle him the opposite direction.
