Stephen Kenny is not hopeful of having Matt Doherty for Ireland's June internationals but is not ruling James McClean out of contention.
Ireland are still awaiting news on their four Nations League fixtures in the summer that were due to get underway against Ukraine on June 4, but those matches remain up in the air.
Doherty, who had been in a rich vein of form on the back of seven successive starts for Tottenham, suffered a knee ligament injury in last Saturday's Premier League victory over Aston Villa.
