I watched the highlights not knowing the result or what had happened, I thought it was the reaction that got him sent off, it looked like a 50:50 ball but that Shawcross got there a fraction of a second too late.
Terrible injury but to suggest it was malicious like Wenger has been is astonishing & while I have no issue really with the red given the severity of the injury, I think it would have been a yellow but for the whole Eduardo history.

not for the faint hearted, but I think it shows it wasn't intentional in anyway
