Marcin Tybura and Viktor Pesta had trained together in the past.
But the heavyweights were not afraid to engage at UFC Fight Night 92.
For Tybura, he got the better of Pesta, delivering a head-kick knockout in the second round for his first Octagon win.
“Thanks to my coaches and my team,” he said. “Everyone who helped me prepare for this.”
Tybura immediately went over to check on Pesta after the fight, saying that the two are “still friends.”
The 30-year-old Tybura is now 14-2 in his career and 1-1 with the UFC after a loss this past April to Timothy Johnson via decision.
