The Flying Knee

Watching the MMA fights last night a fighter, named Jim Ervin, I believe,
won a fight with a flying knee. Just as the other fighter was bending down
for a takedown, Jim Ervin launched himself into the air and brought his knee
up like a piston smacking his opponent solidly in the head and knocking him
cold. Looked like his bodyweight and the piston effect combined caused the
knockout.
My question is did anyone see where that knee landed? Was it on the chin?
