Enes Kanter finally won a championship in New York. It just wasn’t for the Knicks.

The Boston Celtics forward clotheslined and pinned R-Truth to win the WWE 24/7 championship during a taping of “Main Event” prior to “Monday Night Raw” at Madison Square Garden on Monday night. It was WWE’s first televised show at MSG in 10 years.

Kanter, who is an avid wrestling fan and is dating WWE superstar Dana Brooke, celebrated his victory by revealing his Celtics jersey, which brought more boos and chants of “Boston Sucks” down upon him from the Garden crowd. R-Truth, whose real name is Ron Killings, quickly rolled up Kanter to win the belt back – which has to be defended 24 hours a day, seven days a week.

Kanter is the first professional athlete to win the 24/7 championship, an updated version of WWE’s old Hardcore title. The belt, which has been won by numerous WWE superstars, was also held briefly by Fox Sports host Rob Stone.

The championship win came a day after Kanter, who played one and a half seasons with the Knicks before a complicated divorce, went on the “The Full 48″ podcast with Bleacher Report’s Howard Beck and gave his take on why top free agents, such as Kevin Durant and Kyrie Irving this offseason, have avoided owner James Dolan’s club.

“Not many people know that, but players talk. From different teams, they talk,” Kanter said on the podcast. “I’m not blaming anybody. I had an amazing time with the Knicks. But other teammates I talked to or if they’re on different teams, they always said, ‘Amazing city, MSG is amazing. Everything is so good. But the ownership.’ They always keep saying, ‘But the ownership.’”

Kanter, however, said he is not one of the players that does that, saying he recommends the Knicks to other NBA players. He often speaks highly of the franchise.

“I always tell them the Knicks are amazing,” he said. “It’s the Garden, it’s the Mecca. If you win in New York, you’re the king of the world. Some of the players are I guess scared to come here and don’t even want to deal with that.”
