Conor McGregor returns to the Octagon on Saturday after five years away. He meets old rival Max Holloway in Las Vegas in this hugely-anticipated sequel. It’s hard to predict what shape the Irishman will be in after so long out of the ring. But this just heightens the expectation and noise that Hawaiian Holloway will have to silence on the night. Here we preview some of the best bets from UFC 329.GET £20 IN FREE BETS WITH TALKSPORT BET*UFC 329 McGregor vs Holloway 2 TipsMax Holloway to win by KO, TKO or DQ – 17/20 Max Holloway to win in Round 3 – 13/2Conor McGregor bids to make what would be one of the greatest combat sports comebacks ever this weekend if he can beat Max Holloway at UFC 329.The pair rematch 13 years after their first encounter and five years this weekend since the Irishman suffered a career-threatening injury in his trilogy bout with Dustin Poirier.The fact the 37-year-old steps back into the Octagon at all is some feat, snapping his ankle in what was a near career-ending injury in 2021.To do it, McGregor has received no favours from the UFC, booked into a five round main event against one of the top operators in the sport.Holloway has fought eight times since McGregor suffered his injury, racking up nearly 35 rounds of Octagon time.The 34-year-old became BMF champion at 2024’s UFC 300 with a spectacular final-second knockout of Justin Gaethje, defending his belt against Dustin Poirier before losing it in March when outgrappled by Charles Oliveira. Holloway’s road In the midst of this run a move back down to featherweight to try to reclaim his former belt saw Holloway knocked out for the first time in his career by Ilia Topuria. Many believe McGregor’s best chance of victory is via an early knockout, with the 37-year-old known for his incredible left hand that has helped him secure eight of his 10 UFC wins by KO/TKO.The Irishman will be buoyed by the bout being booked at welterweight, the weight class where he earned his only win this decade, a 40 second KO of Donald “Cowboy” Cerrone.The 170lb division is unknown territory for Holloway, who spent time building up his body for the move to 155lbs against Gaethje, after an unsuccessful short notice move up in 2019. While McGregor has filled out in his frame, he is not a natural welterweight, with both men first facing each other as featherweights before becoming champions of that division. McGregor to roll back the years?Ultimately we do not know what a 2026 Conor McGregor looks like inside the Octagon, he looks in tremendous physical condition but how that plays out on fight night is a blind spot.What we do know is that Max Holloway remains a top level striker, with a serious gas tank and will to win.Even in defeat against Oliveira, the Hawaiian defended submission after submission attempt to hear the final bell. It would be a Hail Mary to back McGregor after five years off and while we don’t expect him to disgrace himself, this may be a step too far for him to gain what would be the ultimate comeback victory.GET £20 IN FREE BETS WITH TALKSPORT BET**odds correct at the time of writing and subject to change18+ New customers only.
