In 1982, Cooper was suspended for the equal-longest period in rugby league history, of fifteen months, after he ran in to join a brawl and left three Illawarra Steelers players flattened during a match at Wollongong showground. When imposing the suspension, the NSW Rugby League judiciary chairman, Jim Comans said, "Acts such as these must be obliterated from the game, and I'll begin by obliterating you."[5]
