Aug 27 (Reuters) - The owners of the National Football League are expected to allow some private equity firms to buy up to a 10% stake in a team, CNBC reported on Tuesday.

The NFL's 32 owners are to vote at a special league meeting in Eagan, Minnesota, according to CNBC, and the private equity firms intend to commit $12 billion in capital, to be raised inclusive of leverage.

The NFL is the only major North American sports league that prohibits private equity ownership in a franchise. The NBA, NHL, Major League Baseball and Major League Soccer allow their teams to sell a maximum of 30% of equity to a fund.

Firms initially approved by the NFL will include Ares Management ( ARES ) and Arctos Partners, in addition to a consortium comprising Blackstone, Carlyle, CVC and Dynasty Equity, the report stated, citing people familiar with the matter.

Private equity firms Ares Management ( ARES ) and Sixth Street Partners as well as firms that are part of the consortium declined to comment on the report. The NFL and Arctos Partners did not immediately respond to Reuters requests for comment.

The NFL formed a committee last year to explore changes in its ownership rules. Commissioner Roger Goodell said in March the league was "very close to sort of outlining an approach", with "a lot of work to do to take that approach into reality".

The Washington Commanders was the most recent NFL team to be sold, in a record-breaking $6.05-billion deal.

With team valuations on the rise, private equity could turn out to be an alternative avenue for future league franchise sales.
