Paul McShane is an injury doubt for the Republic of Ireland ahead of their crunch World Cup qualifier against Bulgaria.
The Hull full-back suffered an ankle injury in training on Wednesday and he did not take part in Thursday's light session at Arsenal's London Colney training ground.
The Republic of Ireland coaches will delay any decision on McShane's availability until Friday's training session in Sofia.
McShane is competing with Sean St Ledger, who played against Nigeria last Friday, and John O'Shea for the right-back jersey.
Four players - Shay Given, Robbie Keane, Richard Dunne and Caleb Folan - sat out training on Wednesday but all are expected to be available at the weekend.
Giovanni Trapattoni's men tackle Bulgaria in Sofia on Saturday knowing a win will take them above Italy to the top of Group Eight.
