Pittsburgh Steelers wide receiver DK Metcalf was seen on camera getting into an apparent altercation with a fan during a commercial break in the second quarter of Sunday's game against the Detroit Lions.

As they returned from the break, commentators Jim Nantz and Tony Romo provided brief commentary on the altercation.

CBS Sports rules analyst Gene Steratore provided further analysis of the incident, saying that because game officials did not witness the interaction between Metcalf and the fan, they cannot penalize Metcalf from an officiating or in-game standpoint; the league office will take further action at an appropriate time.

Metcalf ended the first half with one reception for five yards.
