Hearts defender Callum Paterson has been drafted into the Scotland squad ahead of Friday's European Championship qualifier against Republic of Ireland at Celtic Park.

The 20-year-old uncapped right back was brought in by Gordon Strachan after Phil Bardsley – who had been handed an international recall when Alan Hutton injured an ankle – was taken off after nine minutes of Stoke City's win at Tottenham on Sunday with a groin complaint which leaves him a serious doubt.

Johnny Russell got the call to replace Derby team-mate Craig Bryson on Sunday night after the former Kilmarnock midfielder pulled out with a hip injury.

The uncapped 24-year-old has scored four goals in his last four games, including a brace in a 5-0 win over Wolves on Saturday.

Scotland assistant manager Mark McGhee said: “As I sit here now I haven’t been told for certain that Phil isn’t coming.

“Callum Paterson is here.

“The funny thing is I do have a bit to do with Johnny. I watched him last week at Brentford and that point we were looking at people for the squad and they lost 2-1 of course and it wasn’t the best game.

“It wasn’t convincing so we were swaying a bit and then at the weekend he did enough to convince us that he should be part of it so it is a great boost for him.

“If you heard his interviews and how keen he was to be here – that is one of the messages he wants from players.”
