The Broncos were in trouble early. The Chiefs scored on their opening two possessions via a 10-yard Alex Smith touchdown run and a 70-yard Tyreek Hill sprint to the end zone. After the Broncos’ third punt of the first quarter, it looked like the Chiefs would add more. But linebacker Corey Nelson got through on a blitz and hit Smith as he dropped back to throw. Rookie safety Justin Simmons cut underneath the wobbling throw and returned the interception 38 yards to the Kansas City 6-yard line. The Broncos scored two plays later on a Justin Forsett touchdown run to cut the lead to 14-7.
