this was a bit blown out of proportion, based on the reactions you'd think it was some absolutely dreadful shit like Eric Baily's challenge here: https://www.youtube.com/watch?v=KeRZ9vVCazM
but nope, just badly timed attempt to head away the ball and two bodies colliding.
Unfortunate to wrexham, to lose their best striker for like 2 months, but it's kind part of the game.
