(Reuters) - A low hit by Tennessee Titans receiver Harry Douglas on Sunday left the Denver Broncos fuming, with at least one player seeking retribution for what he considered a "dirty" play. Emotions boiled over into a multi-player melee after Douglas lowered his helmet to take out Denver's Chris Harris by the knees during the second quarter of the National Football League (NFL) game in Nashville. "Never had a guy try to end my career like that," Harris said, according to the Denver Post.
