Manchester United captain Roy Keane is set to miss tomorrow's Champions League opener against Panathinaikos at Old Trafford.
The Corkman limped out of Saturday's win at Charlton with an ankle injury and Alex Ferguson, looking ahead to Sunday's match with Arsenal, may opt to give Keane more time to recover.
Paul Scholes (hernia) and Kleberson (dislocated shoulder) are also sidelined, while teenager midfielder Cristiano Ronaldo is expected to make his European debut for the club.
Provisional club: Howard, Carroll, G Neville, P Neville, Silvestre, Ferdinand, O'Shea, Fortune, Butt, Solskjaer, Ronaldo, Keane, Djemba-Djemba, Giggs, van Nistelrooy, Forlan, Fletcher, Richardson.
