According to German News magazin GMX he got hurt by the glass splinters. He got into hospital because of his hand, so I guess it must've been serious enough for him to get into hospital, but that not that serious that he'll miss training/matches for the next few weeks. So he should be fine.
It really was a shock though when I first heard it.
