Luca Connell has been ruled out of the Republic of Ireland's upcoming Euro 2020 qualifiers against Denmark and Gibraltar.
The 18-year-old Bolton midfielder was drafted into Ireland's week-long training camp in Quinta do Lago and manager Mick McCarthy confirmed that he has left the squad after picking up a thigh strain.
McCarthy said that the uncapped Liverpool-born player made a very positive first impression at the warm-weather training camp.
"He was excellent. He has a lovely personality about him," he told RTÉ Sport. "He stood up in training and stood out. I think everybody was impressed with him.
"He's just after saying good-bye to all the lads and each and every one have given him a hug. Everybody took to him as a person and as a player. It's sad for him to be going as it was a good opportunity for him."
After an "excellent" week in Portugal, McCarthy put the players through their paces today and the seniors will play the U21s tomorrow before they depart for the Toulon tournament.
It will be a few days off and then back to the training pitch on Sunday with the Danes away looming.
