Oh my god.

Hull FC forward Joe Westerman left everyone absolutely stunned last night we when decided to repair his dislocated kneecap by slapping it back into place on the field – before getting up and playing on.

Television replays caught the 29-year-old back-rower pulling off the simply remarkable feat of bravery in the final minutes of his side’s 18-10 derby defeat against Hull KR.

“He does that every fortnight.” coach Lee Radford said after the game.

“It has genuinely come out on numerous occasions – he needs some ligaments in there somewhere.”

“It’s a gladiator sport and we had no interchanges left so he stayed out there.”
