Conor McGregor makes his much-anticipated return from a five-year hiatus to face Max Holloway in a rematch on Sunday in Las Vegas.
McGregor beat Holloway, 34, when they met as featherweights in 2013 but will step into the octagon as welterweights at UFC 329.
Former featherweight and lightweight champion McGregor, 37, has won just one of his past four fights and has just two wins in the past 10 years.
Holloway, who also held the featherweight title, will be making his debut at welterweight as he looks to avoid a second loss against the Irishman.
Can McGregor mark his return with a win? Or will Holloway earn revenge?
You can follow all the action from 03:00 GMT on Sunday, 12 July on the BBC Sport website and app.
BBC Sport asked the world of MMA for predictions.
