DETROIT -- Pittsburgh Steelers wide receiver DK Metcalf threw a punch at a fan hanging over the railing at Ford Field in the second quarter of Sunday's game against the Detroit Lions.
The CBS broadcast showed Metcalf talking to a fan in a blue wig who was hanging over the railing in the first row of Ford Field.
After a few seconds, Metcalf reached up, threw a punch at the fan with his closed right hand and walked away.
