MIAMI – Marc Anthony is the latest celebrity musician to join forces with the Miami Dolphins.

The team scheduled a news conference to be held Tuesday in New York for a "major corporate announcement" with Anthony.

It was unclear whether Anthony will become a minority owner. That's what happened last month when singer Gloria Estefan and her husband, producer Emilio Estefan, bought a small stake in the team.

New Dolphins owner Stephen Ross also began a partnership in May with Jimmy Buffett's Margaritaville enterprise, which includes Land Shark Lager. Buffett has yet to accept Ross' invitation to become a minority owner, but the Dolphins' stadium has been renamed Land Shark Stadium for this season. Buffett has also written a song for the team.

NFL commissioner Roger Goodell and ESPN president George Bodenheimer will attend the news conference, the Dolphins said. The team appears on ESPN's "Monday Night Football" on Oct. 12 against the New York Jets, and Anthony may perform at the game.

Officials with the Dolphins and ESPN didn't immediately return calls seeking further details. Anthony's publicist also did not return calls.

Anthony is married to singer-actress Jennifer Lopez. He has sold more than 10 million albums and is also an actor.

Ross, a New York real estate billionaire, completed his purchase of the Dolphins in January from Wayne Huizenga and quickly set out to rebrand the franchise. He has said he wants to fill up the stands with "a blend of entertainment and winning football."
