Steve Tisch, the owner of the New York Giants, has joined the Human Rights Campaign's (HRC) New Yorkers for Marriage Equality campaign.

“As an owner of the New York Giants I'm proud to join the chorus of professionals in sports working for fairness both on and off the field,” Tisch says in his 40-second video released Tuesday.

“All New Yorkers should be able to marry the person they love. Please join me and a super-majority of New Yorkers supporting marriage equality. Now is the time.” (The video is embedded in the right panel of this page.)

Tisch is the fourth celebrity from the world of professional sports to join the campaign. Giants defensive end Michael Strahan, New York Rangers winger Sean Avery and Phoenix Suns point guard Steve Nash have previously recorded videos for the campaign that began last year.

Avery's endorsement created the most controversy – either because he was the first or because of the hockey player's reputation as an agitator on the ice – opening a previously mostly silent discussion on homophobia in professional sports.

The prospects that New York would become the sixth state to legalize gay marriage brightened considerably on Monday when proponents picked up the endorsements of four previously undecided state Senators. However, two more GOP votes are need to win passage in the chamber.
