Australian MMA heavyweight Soa Palelei has retired from the sport at 38 years old after 27 fights.

Palelei was last seen losing to Antonio ‘Bigfoot’ Silva via TKO in the second round of his main card bout at August 1’s UFC 190 pay-per-view (PPV) from Rio de Janeiro. The loss was “The Hulk’s” second loss in his last three fights in his last three fights, as he beat Walt Harris at November 2014’s UFC Fight Night 55 from Australia after Jared Rosholt outpointed him to win by decision at June 2014’s UFC Fight Night 43 from New Zealand.

The brutalizing striker made a name for himself in his home country early in his MMA career, earning his first UFC shot at 2007’s UFC 79, where he lost to Eddie Sanchez. From there “The Hulk” went back to Australia and found success, winning the Australian Fighting Championships (AFC) and K-Oz Entertainment heavyweight championships before returning to the UFC at 2013’s UFC 164.

“The Hulk” is will known for his propensity for finishing bouts, as his aforementioned loss to Rosholt was his only fight that went the distance. Palelei also fought current UFC light heavyweight champion Daniel Cormier for the XMMA heavyweight championship in November 2010.

He also focused on charitable work in Australia, raising money for sick children. Palelei confirmed his work with MMA was not done yet in a statement on Twitter:

“I want to take an opportunity to officially announce my retirement from the sport of Mixed Martial Arts. Thank you to the UFC, Dana White, Lorenzo Fertitta and Joe Silva for giving me a second chance to fight for the organization. I’ve had a great time, but feel it’s time to focus on my family and other career interests. After several months of thought and discussion with my family and my team, we realize our future includes many things in MMA, but active competition in the sport is no longer one of them. This isn’t goodbye, as I will still be very much involved in the sport but just not as a fighter. I want to help further MMA around the world and give my contribution to the sport. I know that I have, and will continue to contribute much to the growth of our sport outside of the Octagon. Stay tuned guys as there is still so much more to come from “The Hulk” ‪#‎WatchThisSpace ‪#‎MuchLove”
