​Newcastle winger Callum Roberts injured his ankle shortly after scoring a late free kick that helped the club's Under-23s reach the ​Premier League International Cup semi-final on Wednesday night.

The side beat Sunderland's Under-23s on penalties after Roberts tied the game 2-2 with a scintillating set-piece finish in injury time, but the winger had to be taken off in the 104th minute and forced to leave the Stadium of Light on crutches while wearing a protective boot thereafter.

He seemed to be in very good spirits, however, tweeting: "Eventful night but buzzing to be in the semi final, lads were excellent."

Roberts, 20, will be assessed by the Magpies medical team on Thursday.

"I think he's just went over on his ankle," coach Ben Dawson said after the game, via the  Shields Gazette. "He just twisted his ankle a little bit and went down. We'll check."

First team head coach Rafa Benitez, meanwhile, congratulated the youngsters via his Twitter account.

"Congratulations to our NUFC U23," the Spaniard tweeted. "Great job, great result and great achievement for the lads and all the staff. Good luck for the next games."
