DENVER -- It's a smackdown fight between World Wrestling Entertainment Inc. and the Denver Nuggets and controversial WWE Chairman Vince McMahon is throwing the first punch.

The battle is over who will get Denver's Pepsi Center next Monday.

According to the Pepsi Center's Web site , WWE is scheduled for an event at 6:30 p.m. on Monday, May 25. The Nuggets are also scheduled to play the Los Angeles Lakers in Game 4 of the Western Conference Finals at 7 p.m. that same night.

Pepsi Center officials told 7NEWS the Nuggets game is definitely on for Monday night.

But WWE was planning a live, internationally televised broadcast -- WWE Monday Night RAW® -- that night and it's already sold out.

WWE said it has held the May 25 date with Pepsi Center since Aug. 15, 2008.

"Even though the Denver Nuggets had a strong team this year and were projected to make the playoffs, obviously Nuggets and Pepsi Center owner Stan Kroenke did not have enough faith in his own team to hold the May 25th date for a potential playoff game," said WWE Chairman Vince McMahon to 7NEWS.

A WWE spokesman told 7News that eighteen tractor trailers, 2 satellite trucks and all the stars' trucks are leaving Cincinnati Tuesday night, headed to Denver, in spite of the double booking.

Pepsi Center officials said it is working with the WWE on a resolution and it is up to WWE to decide if the wrestling event will be rescheduled or moved to another venue.

But the WWE is not budging.

"We are hoping there is a rabbit pulled out of a hat somewhere," McMahon said during an interview with 7NEWS.

Pepsi Center officials said when a decision is reached, the information will be posted on the Pepsi Center's Web site and a news release will be sent out.

A notice on the site posted Tuesday reads: The Denver Nuggets are scheduled to play on Monday May 25th @ 7:00pm. The Pepsi Center is working closely with the WWE and hopes to have information regarding the WWE event at the Pepsi Center soon. Both the Pepsi Center and TM will post information as soon as it is available. NO REFUNDS are available at this time.

On WWE blogs, wrestling fans discussed protesting at the Pepsi Center.

"A contract is a contract," one fan wrote.

But in Downtown Denver, even the staunchest WWE fans said they want the Nuggets in their rightful home for Game 4.

"I love some Stone Cold. I love them all! Wrestling period," said Joseph Thomas, a Denver resident, "But in this situation, McMahon, step back partner. Put your money on the Nuggets!"
