Manny Pacquiao, the only eight-division world champion and also a senator in the Philippines, heard about Senator John McCain's brain cancer disgnosis and issued a statement on Thursday offering his prayers. "I had the opportunity to personally meet Senator McCain in Washington, D.C. in February 2015 and am saddened to hear of his present health issues," Pacquiao said. "My thoughts and prayers go out to Senator McCain for a speedy and full recovery. As with God, anything is possible."

Main Events announced on Thursday that it has signed junior middleweight Frank Galarza (17-2-2, 11 KOs), 31, of Brooklyn, New York, to a promotional deal. Galarza, once a highly touted prospect, is looking to return following back-to-back losses to former world titleholder Ishe Smith last September and Jarrett Hurd, who went on to win a title, in November 2015. "I am just one of those fighters who will never turn down anyone. I will fight anyone," Galarza said. "I wanted to work with Main Events because I have seen what they have done in the past. I like the way they move their fighters. I have seen what they have done with Curtis Stevens and, for me, I just felt that it was a perfect fit. After speaking with (CEO) Kathy (Duva) and (matchmaker) Jolene (Mizzone), I just knew it was right. My goal right now is to get back into the ring and start taking over. I am just grateful that Main Events has given me this opportunity right now. I promise that I am going to give my all and give everything that I have left to give to this sport."

This is what it looked like inside T-Mobile Arena earlier today. It will look markedly different in a mere 36 days when Conor McGregor and Floyd Mayweather make the walk to the ring.

The middleweight world title elimintion fight between Sergiy Derevyanchenko (10-0, 8 KOs), 31, a decorated Russian amateur fighting out of Brooklyn, New York, and Tureano Johnson (20-1, 14 KOs), 33, of the Bahamas,  is scheduled to take place on Aug. 25 and will headline a Premier Boxing Champions card on Fox Sports 1 at a site to be determined. In early June, promoter Lou DiBella, who represents Derevyanchenko, won the purse bid for the bout for $121,100.02 (a 50-50 split between the fighters), easily besting the bid of $62,000 offered by Johnson promoter Golden Boy. Contracts have been signed for the fight and it was scheduled for Aug. 25 with DiBella securing a PBC card from Al Haymon, Derevyanchenko's adviser and the PBC founder. The winner of the fight becomes a mandatory challenger for one of the belts held by Gennady Golovkin.

The Premier Boxing Champions prime time tripleheader on Fox on Saturday night from the Nassau Veterans Memorial Coliseum in Uniondale, New York, which was headlined by welterweight Omar Figueroa Jr.'s three-round destruction of Robert Guerrero and featured two other mismatches with little name recognition (light heavyweight Marcus Browne's second-round crushing of Seanie Monaghan and heavyweight Adam Kownacki stopping Artur Szpilka in four), hit a new low for PBC on Fox cards. According to Nielsen Media Research, the telecast (8 p.m.-10 p.m. ET, which overlapped only in the final 10 minutes with the HBO card) averaged just 886,000 viewers and peaked above 1 million viewers in the final half hour (exact peak audience was not available yet). This was by far the weakest prime time PBC on Fox card and the first to average fewer than 1 million viewers. It also drew the fewest viewers of any program on network TV in prime time that night.

Conor McGregor was fantastic in London, and better than Floyd Mayweather overall in the tour. Mayweather clung to basically three or four shticks, which felt very tired by the fourth stop. Tour as a whole had big swings and misses. It was fun, but I think EVERYONE, is happy it's concluded today.

There is a massive crowd outside of Floyd Mayweather and Connor McGregor's hotel in London before their press conference today.
