I always sort of shudder at the knee slide celebrations. If you tried that in park football you'd end up with a bit of rock embedded in your patella. And that's going to HURT in the morning.
I agree, Tom.
As someone who has had bilateral knee replacements, I visibly cringe and break out in a sweat when I see these celebrations.
Knees can such a problem for sportsmen, I am surprised they risk them in this way.
Wonder if we'll see them banned by a club........just in case!
