It’s not every day you get a heavyweight heel hook, but that’s what fans got Friday at PFL Playoffs 1 . In a heavyweight showcase bout that served as the featured prelim, Sergey Bilostenniy  submitted Tyrell Fortune with a gnarly heel hook at 2:00 of Round 1. The finishing sequence was an elongated leg lock battle, which Bilostenniy (12-3) eventually won in destructive fashion.
