It's no secret that Conor McGregor is one of the larger guys in the featherweight division. Standing 5-foot-9, the former cage warriors lightweight champ has already spoken about eventually moving back up to 155 lbs in the future. He's set for an interim title fight this weekend though, and it looks like he's in for another tough cut to 145 lbs.

"He's a very big guy. I was impressed with how big he is," Chael Sonnen told Jim Rome as he spoke about his time with McGregor at ESPN. "I was like 'Conor, what do you weigh?', he said 'I'm around 172 lbs'. He's got to be 145 lbs in eight days."

"He's going to be a little bit bigger than Chad. I don't know if that helps or not. It might slow him down. He's a big guy," he continued. "I've (cut that much weight) before, but I'm considerably bigger. Percentage-wise, I wouldn't have to lose quite as much."

"I don't know how he's going to do it. He's very lean. He has a very busy schedule. He's training at Las Vegas. He was just in LA with Conan O'Brien last night. He's in New York for Reebok a day before that. He was in Connecticut the day before that," he said. "One, how does he do the weight? And two, how does he find the time? I don't know."

McGregor's performances in the UFC doesn't seem to have been hampered too much by the cuts in the past, but he hasn't exactly been thoroughly challenged or pushed in those bouts either. Will it be different this time against a tough wrestler in Chad Mendes?

For those who remember, McGregor did make 'championship weight' on his last bout against Dennis Siver, but he also looked completely drained in the process. With IVs set to be banned come October, it's not all too farfetched to think that Conor's eventual move to 155 lbs could come soon.
