The UFC is up for sale, and the Kraft Group, which owns the Patriots and the Revolution, may be contributing to the bid that ultimately lands the Ultimate Fighting Championship. 

According to ESPN's Darren Rovell, the Kraft Group has agreed to invest in the WME-IMG bid to purchase UFC. Per Rovell, WME co-chair Ari Emanuel has been asking investors "to chip in $25 million to $50 million."

WME-IMG's bid is being made in conjunction with Dalian Wanda Group. Their primary competitor is China Media Capital. Rovell is reporting that both groups are bidding in the $4.1 billion range. 

One interesting link to a potential Kraft Group investment, pointed out by our pals at Pro Football Talk, is that the money spent to buy the UFC may be turned around to purchase the Oakland Raiders. 

Frank and Lorenzo Fertitta, brothers with ties to Las Vegas, own 81 percent of UFC. They could potentially be interested in buying the Raiders from owner Mark Davis and move the franchise.

But UFC president Dana White has denied that the Fertitta brothers are interested in purchasing the Raiders.

"No. That’s absolutely false," White told The Dan Patrick Show last month. "That’s not true. It’s very well known the Fertitta brothers are lunatics about football. They love football. What they’ve done to help Bishop Gorman become the No. 1 high school team in the country, Lorenzo’s son plays at Notre Dame, Lorenzo’s other son plays at Villanova. They’re definitely football guys, but they’re not looking to buy a football team right now."
