It turns out the incident between them was over a handshake.

Sources close to the incident stated Ertz initially wanted to shake Sirianni’s hand and could tell the coach was agitated by the loss. Instead, he decided to give him a high five.

Nick Sirianni became enraged over the intensity of Ertz’s hand slap and mocked him since he only had one catch and did close to nothing to contribute to the Commanders’ victory.

Ertz took exception and got in Sirianni’s face, but they were separated.

This was shocking news since Ertz spent eight-plus seasons with the Eagles before he was traded to the Arizona Cardinals midway through 2021.

He remains second in franchise history in receptions (579) and fifth in receiving yards (6,267).
