Pittsburgh Steelers star wide receiver D.K. Metcalf undoubtedly crossed a line that goes beyond the gridiron. He let his emotions get the best of him in the team's pivotal interconference clash with the Detroit Lions and struck an opposing fan.
The CBS broadcast captured Metcalf confronting a Lions supporter on the sidelines in the second quarter of the Steelers-Lions showdown in Detroit. Whatever was said evidently didn't sit well with the two-time Pro Bowler, so he ended the conversation by throwing a punch.
