Uefa has handed Holland striker Ruud van Nistelrooy a two-match ban for insulting behaviour towards referee Anders Frisk.
The 28-year-old was unhappy at Frisk's performance during Holland's semi-final defeat to Portugal on Wednesday.
Van Nistelrooy accused Frisk of ruling "everything in favour of Portugal" and of being a "home whistler".
The Dutchman has until Monday to appeal against the ban, which could rule him out of two 2006 World Cup qualifiers.
Unless he is successful, Van Nistelrooy will miss Holland's home game against the Czech Republic on 8 September and FYR Macedonia away on 9 October.
