Hull City manager Steve Bruce has claimed innocence regarding his altercation with Sunderland counterpart Gus Poyet in the 1-1 draw at the KC Stadium on Tuesday night.
The Black Cats boss approached Bruce in the dugout after Jack Rodwell had been yellow-carded for diving as he was on his way to the stands.
Poyet had been sent from the touchline after questioning referee Mike Dean's decision to book goalscorer Rodwell for simulation and Bruce couldn't understand why he was the subject of the Uruguayan's frustration.
"The big contentious issue was Rodwell running through and, from where I was standing, he took a run, a jump and a dive," he told Sky Sports.
"The referee got it right, but Gus' reaction means he obviously thought it wasn't right. You'll have to ask him the rest of it.
"Why has he come over to me? I don't really know what I'm supposed to have done.
"These things, however, do happen in the heat of the moment. These things do happen in big games and today was a big game.
"I suppose I'm not flavour of the month after (Stoke City's Mark) Hughes had a dig this afternoon and Gus tonight, but I hope he is OK.
"My door is always open, but I'm not sure what I've done to warrant what has happened. You better ask Gus that."
