Antonio McKee said it just wasn’t right. Same went for his son A.J. McKee.

Not only did the Long Beach father and son emerge from Bellator 228 on Saturday with knockout victories, but each also showed a healthy dose of integrity.

Antonio McKee, 49, returned $500 to opponent William Sriyapai after his 47-year-old opponent was fined 20% of his purse for missing weight for their 165-pound fight at The Forum.

When Antonio learned he would receive half of the 20% and the California State Athletic Commission would receive the other half, he balked.

“Because it’s not right. I understand you penalize him for not making weight,” Antonio said Monday, two days after recording a second-round TKO of Sryapai, who weighed in at 167.9 pounds. “Give 10% to the athletic commission? Give to me. Give to the fighter.

“Why (does the CSAC) benefit off an additional 10% of a fighter’s purse? It doesn’t make sense to me. What stress did it put on them? It didn’t cost them any time or paperwork.”

Antonio was paid $25,000 for Saturday’s fight to $5,000 for Sriyapai, according to salaries released by the CSAC. Those are base salaries reported to the CSAC and do not reflect compensation in terms of discretionary bonuses, sponsorship deals or any pay-per-view income.

Antonio said the CSAC didn’t have a good answer as to why it would receive part of Sriyapai’s purse – “They said, ‘That’s good question,’” he said – but he said his opponent was grateful.

“He said, ‘Man, you’re really a standup guy, McKee. Thank you,’” Antonio said. “It’s not right. I stand for what’s right.”

Speaking of standing, his son did it during his fight sooner than he had to, but exactly when it was necessary.

A.J. McKee needed just eight seconds to knock out Georgi Karakhanyan in their opening-round bout of the $1 million Featherweight World Grand Prix. After dropping Karakhanyan with a massive overhand left, A.J. jumped on him and began raining punches.

After the sixth strike, A.J. got up to celebrate before the referee had even jumped in to stop the fight and make the McKees the first father and son to fight and win on the same card of a major MMA promotion in the United States.

“I knew when he had enough. He wasn’t defending himself,” A.J. said late Saturday night. “I’m not out there to maliciously hurt people. At the end of the day, I know when someone had enough and I’m not gonna continue to pounce someone.”

During Saturday night’s selection show to fill out the quarterfinals of the Featherweight World Grand Prix, A.J. had the first pick and opted to fight next in December, reportedly in Hawaii. Later, Derek Campos chose A.J. as his next opponent.

The other quarterfinal fight on their side of the bracket is Redlands’ Darrion Caldwell vs. Adam Borics in January at The Forum. The other side of the bracket features Daniel Weichel vs. Emmanuel Sanchez in February and champion Patricio Freire vs. Pedro Cavalho in March.

Antonio was proud of his son’s victory and how he went about it. In fact, Team Bodyshop went 4-1 on the night, including Adrian Najera, who won the final post-lim fight but suffered a broken arm and broken leg for his efforts.

The McKees didn’t leave The Forum until visiting their teammate in the ambulance for several minutes before Najera was taken to the hospital just after midnight.

The elder McKee was just happy to part of something historic.

“I’m forever grateful and thankful for everything. And I’m proud of my son for going out there and doing exactly what he said he was gonna do,” Antonio said late Saturday night. “It gets no better. I can go home and sleep for a couple weeks now.”
