Munchak could receive a fine for his role.
Pittsburgh lost 15 yards late in the first quarter of their 18-16 AFC wild-card win over Cincinnati when Munchak, the offensive line coach, got tangled with Nelson, who came flying into Pittsburgh's sideline. Nelson was trying to tackle running back Jordan Todman, who ran for 14 yards on the play.
Nelson bumped into Munchak and the two appeared to push each other. Munchak caught some of Nelson's long hair with the same hand that carried the offensive play sheet. The two were penalized by officials, who deliberated, then gave Munchak a penalty. It was difficult to tell whether Munchak's hair grab was malicious, but Bengals corner Adam Jones called Munchak's behavior "uncalled for" today on the Dan Patrick Show.
"He should have been escorted to the locker room," Jones said. "If a player would have done that ... I'm quite sure he would have been kicked out the game."
Munchak is one of two Steelers assistants under review by the NFL. According to ESPN NFL insider Adam Schefter, outside linebacker coach Joey Porter will get fined for walking onto the field in the game's final seconds while receiver Antonio Brown was injured from a Vontaze Burfict helmet hit. Jones got a 15-yard penalty for trying to shove Porter, moving the Steelers closer to field goal range. Chris Boswell won the game with a 35-yard field goal.
Sources say teammates have been joking with Porter for his controversial role, praising him for helping them win and calling him "Jerry" Porter since that's what Pacman called him in his profanity-laced postgame video on social media. One Steelers player jokingly called Porter "definitely the MVP" of the game.
