"Since he was drafted back in 2016, Andy has developed into one of the best fullbacks in the league," Broncos general manager John Elway said in a statement. "He's exactly what you look for in a fullback -- tough, reliable and a versatile part of not only the offense but also our special teams. It's nice to see how Andy's hard work has paid off, and we look forward to his continued impact on the Broncos."
