Mayweather-McGregor Final PresserFormer world champion Floyd Mayweather and MMA star Conor McGregor faced off Wednesday at the final press conference before their PPV clash on Saturday at the T-Mobile Arena in Las Vegas.

Conor McGregor: We are prepared for twelve three minute rounds on non-stop pace. I will go forward and I will put the pressure on him and break this old man. Trust me on that. Eight-ounce gloves I think he made a big, big error. I don’t see him lasting two rounds…I’m going f__k this boy up.

Floyd Mayweather: Pacquiao’s got bomb, Canelo’s got bombs, Shane Mosley had bombs, and for those guys it was all in vain. One thing about me, I’ve got a granite chin. Remember this. The same way you give it, you have to be able to take it.

Jones tests positive for steroids at UFC 214, not yet stripped of title‚Äč

Jon Jones' laundry list of trials has itself another addition.

"Bones" has been flagged by the USADA for a potential doping violation stemming from a sample collected after he weighed in for his rematch with Daniel Cormier at UFC 214 on July 28, the promotion announced Tuesday.

He's been provisionally suspended as a result, although he has yet to be stripped of the title he took from Cormier via third-round TKO, UFC president Dana White told ESPN's Brett Okamoto.

Jones tested positive for anabolic steroid Turinabol , a substance carrying a penalty of two years for first-time offenders and four for repeaters. The development marks his second run-in with the UFC's anti-doping partner in the past year. The 30-year-old saw a rematch with Cormier at UFC 200 scrapped just three days out when he tested positive for estrogen blockers, an infraction he blamed on a tainted sexual enhancement pill. He was subsequently handed a one-year ban, last month's clash with Cormier coming mere weeks after his penance had expired.

The oft-troubled New York native has been stripped of the title once before in 2015 due to a hit-and-run incident.

NSAC to Vote on Whether Lighter Gloves to be Used for Mayweather – McGregor

Currently Floyd Mayweather and Conor McGregor are scheduled to wear 10-ounce gloves in their August 26th contest, but that could change.

Typically, 10-ounce gloves are used for fights that are fought at 154 pounds, which is the weight class that is for the Mayweather – McGregor bout. But, according to a report from Sky Sports, Mayweather and McGregor are going to request that 8-ounce gloves be utilized for the fight. As a result, the Nevada State Athletic Commission will consider the request and will vote on it, August 16th.

Mayweather – McGregor will be hosted by the T-Mobile Arena in Las Vegas, Nevada
