Holland coach Marco van Basten has trimmed his provisional European Championships squad from 29 men to 26 ahead of revealing his final selection later this month.
Ajax defender Urby Emanuelson, Kew Jailens of AZ Alkmaar, Hedwiges Maduro of Valencia and PSV Eindhoven forward Danny Koevermans have all been dropped from the squad, with Sevilla defender Khalid Boulahrouz invited to join a pre-tournament training camp.
Boulahrouz has only just returned to action after a long period out with a groin injury and the Holland coaching staff want to assess his fitness level.
Van Basten's provisional squad had already been reduced by one following the withdrawal earlier this week of AC Milan midfielder Clarence Seedorf, who claimed to be unhappy with his role in the Dutch set-up.
Real Madrid trio Ruud van Nistelrooy, Arjen Robben and Wesley Sneijder, Manchester United goalkeeper Edwin van der Sar and Celtic striker Jan Vennegoor of Hesselink will join up with the squad later this month as all have club obligations to fulfil.
Van Nistelrooy, Robben and Vennegor of Hesselink will join with the squad on May 23 while Van der Sar and Sneijder will arrive three days later.
Van Basten's final 23-man squad will be announced by May 28 at the latest.
Holland, the 1988 European champions, have been drawn alongside Italy, France and Romania in Euro 2008 Group C.
Revised Holland squad: Boschker (FC Twente), Van der Sar (Manchester United), Stekelenburg (Ajax), Timmer (Feyenoord); Bouma (Aston Villa), De Cler (Feyenoord), Boulahrouz (Sevilla), Heitinga (Ajax), Mathijsen (Hamburg), Melchiot (Wigan), Ooijer (Blackburn); Afellay (PSV Eindhoven), Van Bronckhorst (Feyenoord), Engelaar (FC Twente), De Jong (Hamburg), Landzaat (Feyenoord), Sneijder (Real Madrid), Van der Vaart (Hamburg), De Zeeuw (AZ Alkmaar); Babel (Liverpool), Huntelaar (Ajax), Kuyt (Liverpool), Van Nistelrooy (Real Madrid), Van Persie (Arsenal), Robben (Real Madrid), Vennegoor of Hesselink (Celtic).
