I think he just slipped on the grass, as did many other players
did throughout the tournament so far. I believe there's some
complaint from a few of them that the grass is too slippery.
Anyway, he's a first-timer at the World Cup, so they'll probably
like to give him easier and less publicised matches to gain some
experience first. If he does well in this one he might well be on
the way to becoming our own Pierluigi Collina.
