Republic of Ireland manager Martin O'Neill has major injury concerns ahead of Friday's qualifier with Scotland after Marc Wilson and James McCarthy suffered suspected hamstring injuries. 

O'Neill was present in White Hart Lane as he watched Stoke take on Tottenham Hotspur where Wilson left the field with a suspected hamstring problem after 25 minutes.

Everton midfielder McCarthy lasted the full 90 minutes of their 1-1 draw with Sunderland but manager Roberto Martinez said afterwards that he will be assessed. 

"He was feeling his hamstring towards the end of the game but he wanted to stay on the pitch because we had used all three subs," he said.

“It is a bit of a concern because he had the same injury a few weeks back when he missed the game against Manchester United and it is in that area. We are hoping that it is more fatigue than a soft tissue problem.

“We will assess him in the morning

Jon Walters scored for Stoke City, also in the first half.

Darron Gibson was introduced as a substitute for Everton, while Seamus Coleman returned for the Toffees. 

Ireland take on the Scots at 7.45pm this Friday in Celtic Park.
