Nottingham Forest and former Wolves forward Morgan Gibbs-White – who celebrated in front of the away end after his team won on penalties, was at the center of the chaos, clashing with some of his former teammates.
Stewards were forced to intervene, and both clubs will almost certainly be fined by the English Football Association.
Forest coach Steve Cooper declined to comment on the incident.
“I am not going to deny there wasn’t one because there was but why it happened and how it happened and what happened, if I speak about it I wouldn’t be completely clear because I don’t know,” he said.
“So I shouldn’t really say anything.”
He did, however, admit that Dean Henderson’s inability to play in the semi-final against Manchester United reduces his team’s chances.
The on-loan goalkeeper, who saved penalty kicks from Ruben Neves and Ireland U-21 international Joe Hodge, will be ineligible for the two-leg last-four tie against his parent club unless United gives him written permission to play.
“It’s unfortunate. He’s part of our group, he is so invested in the group and how we work, what we’re trying to accelerate in terms of what we want to become”.
“To do that you need a really good goalkeeper. Not only is he committing as a goalkeeper, he is buying into being in the city and the greater good of the club”.
“It has put a dampener on it for me.”
