Wilkinson will also miss the rest of the 2023 PFL season.A recent tweet by MMA journalist Alex Behunin confirmed that 'Razor' is the latest PFL fighter to fail a drug test. His last opponent Thiago Santos and Krzysztof Jotko were handed temporary suspensions last month along with suspensions for Bruno Cappelozza and Rizvan Kuniev.Given the number of fighters failing drug tests, fans and Twitter users expressed their concern over the promotion's future in the comments section of the news post.Alex Behunin@AlexBehuninSome late night breaking news:2022 PFL Champion Rob Wilkinson is out of his fight next week due to failed drug testmmamania.com/2023/5/31/2374…19927Some late night breaking news:2022 PFL Champion Rob Wilkinson is out of his fight next week due to failed drug testmmamania.com/2023/5/31/2374…One fan joked about the PFL's roster, saying:"PFL ain’t even gonna have a roster."dpitlock@NTBSdan@AlexBehunin PFL ain’t even gonna have a roster3@AlexBehunin PFL ain’t even gonna have a rosterAnother fan redefined the PFL abbreviation, stating:"PED Fighting Championship."C$D Lunch77@Lunch77Beatz@AlexBehunin PED Fighting Championship291@AlexBehunin PED Fighting ChampionshipOne user wrote:"That's like half of their roster who popped by now lol.
