John O'Shea has been given the green light to join up with the rest of the Republic of Ireland squad by Sunderland's medical staff.
The defender had been classed as a doubt for the European Championship this summer after limping off against Manchester United on Sunday.
But fears he had aggravated a long-standing calf problem were dispelled following a post-match scan which revealed it was damaged to his ankle instead.
And while he is unlikely to be fit for the friendly against Bosnia-Herzegovina at the Aviva Stadium on Saturday, he has been given permission to join up with rest of Giovanni Trapattoni's squad in Malahide.
A club spokesman said: "John suffered a knock to his ankle in training prior to the Fulham game, which he aggravated slightly in Sunday's game against Manchester United.
"He was taken off as a precaution and following positive results from a scan last night, he will meet up with the Republic of Ireland squad as scheduled next week."
