RingTV.com’s Lem Satterfield has a story up this morning confirming a Sports Illustrated report from yesterday in which Top Rank promoter Bob Arum stated that Manny Pacquiao will most likely fight on June 9, in a new outdoor stadium in Las Vegas, against an opponent other than Floyd Mayweather Jr.

Arum’s comments to RingTV.com left open at least the possibility that a fight with Mayweather could still be made for the end of May:

“If we can’t do a fight with Mayweather at the end of May, yes we will do a fight with somebody else on June 9,” Arum told RingTV.com. “That’s correct. We’re still optimistic, or somewhat optimistic, that we can do a fight with Mayweather at the end of May.”
