I thought that the Ivory Coast (CIV) goalkeeper's "injury" was quite interesting from a LOTG point of view.
For those who didn't see it, the shootout had gone through all ten outfield players and Bouboucar Barry, the CIV goalie, having just saved the Ghana goalie's penalty kick went down claiming to be injured. If he had stayed down and insisted he could take no more part then as far as I can see from the laws, he could have been replaced but this would not be compulsory - the laws say "may be replaced" not "must be replaced". Therefore, if Barry had insisted that he was too injured to take the kick then one of the other players could do so; CIV could replace their worst penalty taker with their best for this crucial kick!
Is there anything that I have missed in law that would stop this happening?
