The night of April 29 should be the culmination of a dream for unbeaten heavyweight Michael Grant.

On that night he will get a shot at Lennox Lewis’ undisputed heavyweight title at Madison Square Garden — once known as the mecca of Boxing.

But 6-foot-7, 240-pound Grant is going into the ring with trepidation — and not because of Lewis, according to his manager, Craig Hamilton.

“We’re definitely wary of this fight, and it’s largely because of the [New York State] Athletic Commission,” Hamilton said.

“They certainly didn’t oversee the [Evander] Holyfield-Lewis fight very well, did they?”

In that fight, on March 13, 1999, most observers believe, the heavyweight title was stolen from under the noses of the NYSAC despite the presence of an unprecedented 25 commission inspectors.

That is because NYSAC accepted without question the judges provided by the WBC, WBA and IBF, and did not require any of them to take out New York state licenses.

After IBF judge Jean Williams scored the fight for Holyfield and WBC judge Larry O’Connell scored it even — resulting in a highly unpopular majority draw — the commission had no power to punish any of the judges.

For the upcoming championship bout, the commission says it will insist on having final say over the selection of judges.

“I don’t have great faith in the commission when it comes to picking judges,” Hamilton said. “They better not just accept whoever the sanctioning organizations give them. Those people have a vested interest in keeping their champion.”

Hamilton’s history with the commission is not a positive one. Recently, it voided a managerial contract Hamilton and his partner, Elvis Phillips, had with junior middleweight Andrew Murray after Murray complained his managers had overmatched him against Derrick Graham, who dealt him his only career loss.

“Everything we could have done for Andrew Murray, we did,” Hamilton said. “He was given stipends, he was advanced money. In some cases we didn’t take our managerial share. He was treated fairly.

“For the commission to void a contract just because a kid loses a fight is ridiculous.”

Hamilton said Murray, in fact, breached his contract by signing with another manager before ending his deal with Hamilton and Phillips.

“The kid did the wrong thing and the commission backed him on it,” Hamilton said. “The next time I sign a kid to a contract, this is the last commission I would do it with.”

Phillips believes there was another reason for the ruling. “I’m absolutely convinced they stuck it to me for Vaden,” he said.

Phillips was referring to an April 1998 incident in which the commission failed to notice that Edwin Rodriguez, the opponent it had approved for Paul Vaden to fight at Yonkers Raceway, was on the suspension list.

The fight was canceled at the last minute and Vaden, who had flown in from San Diego, was out training and travel expenses.

“The commission never apologized for embarrassing me with the kid or costing us any money,” Phillips said. “I went to the papers with the story and they held it against me. I knew I had something coming to me.”

“I hope that’s not the reason [for the Murray ruling], and I hope it doesn’t bounce back on Michael,” Hamilton said.

“All I know is, we should be excited about this fight, and we are. But we’re also worried.”
