Scotland defender Scott McKenna has been ruled out of the upcoming European Championship qualifiers with a hamstring injury that will keep him side-lined for up to eight weeks.
The 26-year-old Nottingham Forest player was taken off after just seven minutes of the English Premier League game against Fulham on Saturday.
A scan has now revealed that he will be out for between six to eight weeks, with Steve Clarke’s men set to take on Cyprus and Spain in just over five weeks.
The former Aberdeen star has 29 caps and started in the Nations League wins over Ireland and Ukraine in September.
Scotland’s European Championship campaign kicks-off against the Cypriots on March 25 in their first group match in a section that also includes Norway and Georgia.
Clark is already without veteran goalkeeper Craig Gordon for next month’s double header after the Hearts skipper suffered a double leg break on Christmas Eve.
Sunderland forward Ross Stewart is also missing with an injury that is set to keep him out for the rest of the season.
McKenna has made 18 league appearances for Forest this season as they sit 14th in their first season back in the EPL.
