Rory MacDonald has made a very bold accusation against one of his former opponents.

Just over two years ago, then-UFC welterweight champion Robbie Lawler defend the title against McDonald in a war for the ages at UFC 189. It was truly a classic slugfest.

At the event of the day, MacDonald fell short in the bout by losing it via fifth-round TKO after being up on the scorecards in a fight that many have called one of the greatest fights in MMA history.

Since that bout, MacDonald has gone on record by saying that this bout has help reshaped his career. On Thursday, MacDonald said in a Reddit ‘Ask Me Anything’ that he believes Lawler was using banned substances.

“I’m convinced he was,” MacDonald answered when asked if he thought Lawler was on performance enhancing drugs during the fight.

Although the former UFC fighter did not go further with his comments on the matter, the comment wasn’t his only remark about PED use in the sport. MacDonald later said that it was “a true shame to see grown-ass men and women” using banned substances in the MMA, and when asked about Jon Jones’ potential USADA violation at UFC 214, MacDonald said that Jones was “shameful, like every other guy that does this crap and hides it, yet gloats during victory.”

MacDonald signed with Bellator MMA last year and is looked at one of the best prizes that the promotion has picked up. By looking at his status, MacDonald is widely regarded as one of the best welterweights in the world today and owns a pair of victories over the last two men to fight for the UFC welterweight belt. He holds a win over reigning champion Tyron Woodley and UFC 214 title challenger Demian Maia. MacDonald’s victory over Woodley was a one-sided affair in 2014.
MacDonald said that he “would submit or TKO” Woodley if the two ever met again.

“I think Tyron is a very strong competitor,” MacDonald wrote. “Very strategic, athletic, but I am aware of his weaknesses also.”

“I believe if my next fight is for the title, I will beat (Bellator welterweight champion Douglas) Lima then fight the winner of Mousasi vs. (Bellator middleweight champion Rafael) Carvalho,” MacDonald wrote.
