It all started out pretty light hearted with jostling, joking and fighting talk, but then descended into ACTUAL fighting when Jon Clark fell to the ground during play.
Everything was quite fast so it's hard to tell exactly what happened, but it looks like Jon fell over and was rather angry, opposing team member Jake ran over, but Pete intervened to stop him, resulting in Pete and Jake having a shoving match while teammates tried to separate them.
In the end, Tommy Mallet reminded them: "Light hearted boys. Come on, man!"
The official TOWIE Twitter account shared a clip of the row with the caption: "Oof. Nobody wants to see that on the football pitch. Sort it out, ref. #TOWIE."
Pete replied: "All fun and games."
We're guessing that means it was all heat of the moment and no hard feelings.
As an FYI, it was Team Real - Liam, Jake, Tommy, Dan and Diags - who won, 6-0 to Team Alpha, which was Lockie, Mike, Pete, Jon and Chris.
