Some pro wrestling submission holds are a bit silly. The Octopus Stretch? The Muta Lock? The Clover Leaf? It's hard to suspend disbelief when we see wrestlers tap to those.
The calf slicer (or, as AJ Styles calls it, the Calf Crusher), on the other hand, is a real and devastating submission move that sees the attacker place their leg behind their opponent's knee joint and bend their leg over it, compressing the calf and potentially destroying it if held too long.
Don't believe it? Well, check out Brett Johns' submission win in the UFC from Friday night.
Countering a single-leg takedown attempt from Joe Soto, Johns (15-0) rolled backward while isolating Soto's leg. With the position already squared away, Johns grabbed hold of Soto's foot and started pulling, forcing a frantic, screaming submission.
It was the most impressive finish on a solid night of MMA, and a sequence that showed Styles' signature move is a legit killer.
