In a rare moment of vulnerability, Conor McGregor opened up about the harrowing experience of witnessing the death of his teammate's opponent in the ring. Back in 2016, during a fight in Dublin, McGregor watched as his stablemate Charlie Ward, a talented featherweight champion, earned a third-round TKO victory over a young fighter named Joao Carvalho. The seemingly routine fight night turned tragic when Carvalho, who had suffered a brutal beating and excessive bleeding, tragically passed away from brain injuries less than 48 hours later. An inquest later revealed Carvalho had endured a significant number of blows to the head during the fight.McGregor, in a conversation with Men's Health, spoke about the profound impact this incident had on him:"How do I feel?... It’s f**ked up, I wasn’t just watching that fight. I helped train a guy to kill someone, and then someone wound up dying. This is a f**king dangerous game. People call it a sport, but it’s fighting. I’m just making sure it ain’t me. And that’s f**ked up.”Check out the clip from the fight between Charlie Ward and Joao Carvalho below:When Conor McGregor feared his career was over after leg injury in Dustin Poirier rematchConor McGregor revealed in his Netflix documentary that he feared his career was over after suffering a horrific leg injury during his fight against Dustin Poirier at UFC 264 in July 2021.The much-anticipated trilogy bout ended abruptly after McGregor's leg buckled beneath him during the first round. A doctor's stoppage awarded the victory to Poirier, leaving McGregor with a fractured tibia that required surgery.A clip shared by McGregor on his Instagram shows him reflecting on the injury in the documentary: “I thought it was over as well, that’s why I flipped into a different mode. Now, it was the adrenaline as well and I know it would’ve calmed down and part of me is thinking ‘Jesus, imagine it was just taken from me like that… I would be a different person and it was a bit scary, to be honest. But it’s McGregor forever. That’s it! It’s done. It’s McGregor forever and don’t you forget it.” [H/t:Talk Sport]Check out the clip shared by Conor McGregor below: View this post on Instagram Instagram PostThankfully, McGregor has fully recovered and is set to make his long-awaited return to the octagon on June 29 at UFC 303 in Las Vegas.
