Hull City Football Club star Craig Fagan faces three months on the sidelines.
The former Derby County player was on the wrong end of a Danny Guthrie challenge in the closing stages of the 2-1 win at Newcastle United, and scans have revealed a broken leg.
"It cannot be tolerated, it needs to be kicked out of the game,” manager Phil Brown told the Hull Daily Mail of the challenge. "The end product is him putting a fellow pro in a cast, it's just not right.
"That's the horrible side of the game. I don't care what is going on at Newcastle, you cannot tolerate this. If I go back to the incident, my players were killing time in the corner.
“Every Premier League club does that, no matter who you are. In the process of doing that, someone has decided to take the matter into his own hands and lashed out at Craig Fagan."
