Actor Varun Dhawan says he is sad but happy with the retirement of Conor McGregor and says the professional mixed martial artist and boxer had changed the sport. McGregor on Monday announced his surprise retirement on Twitter and wrote: "Hey guys quick announcement, I've decided to retire from the sport formally known as 'mixed martial art' today. I wish all my old colleagues well going forward in competition. I now join my former partners on this venture, already in retirement."

Varun on Tuesday replied to his tweet, saying: "I am sad but happy in a way. This guy had his run changed the sport. He's a legend no two ways about it. Thank you Conor"
