Marcin Prachnio is a Polish professional Mixed Martial Arts (MMA) fighter currently competing in the UFC’s Light Heavyweight division. He was born on April 14, 1988, in Olsztyn, Poland.

Prachnio had a successful amateur career before turning pro in 2013 at the age of 25. In his first two years as a professional fighter, he compiled an impressive 10-2 record with all wins coming by way of knockout or submission. This success earned him a spot on The Ultimate Fighter: Team Jones vs. Team Sonnen TV show in late 2013 and early 2014 where he eventually made it to the semifinals before losing to Ian McCall via unanimous decision.

After that loss, Prachnio continued to rack up more wins and compiled an overall 12-3 record before signing with the UFC in September 2016 at 32 years old. At this point he moved down from middleweight to light heavyweight due to struggles making weight for fights at 185 lbs., which has now become his fighting weight class since joining the promotion three years ago.

Prachnio has gone 4-4 inside the cage since debuting with the promotion back in October 2016 and his most recent outing was against Magomed Ankalaev last December at UFC Fight Night 163 when he suffered a first round TKO loss after taking some punishing ground and pound strikes from his Russian opponent only five minutes into their fight.

Outside of fighting Prachnoi is very active on social media where he often posts inspirational quotes about hard work and dedication as well as status updates about how much time he spends training each day or week leading into fights against opponents like Ankalaev or Paul Craig whom he faced back in June 2018 when both men were ranked fourth and third respectively according to official UFC rankings heading into their co-main event bout which ended up being won by ‘The Bear’ via split decision after three rounds of action inside Russia’s Olympic Stadium Moscow Arena (Olimpiyskiy).

At 31 years old Marcin Pracheoni is still very much within his peak fighting years but will need some big wins if wants make any real waves within one of MMA’s toughest divisions going forward – especially considering that four out of his eight bouts have ended either split decisions losses or no contests due lack punches below belt slips over past few months alone!
