Nathan Patterson has joined fellow defender Kieran Tierney through injury for Scotland’s World Cup play-off semi-final with Ukraine.
Everton manager Frank Lampard said right-back Patterson’s season was “probably” over after an injury at the training ground that required surgery.
This follows Monday’s news that Tierney Arsenal are “not looking good” following the knee injury suffered by Scotland.
“Nathan Patterson will be out for a period of time,” said Lampard.
“He will have minor surgery on his ankle this weekend.”
After impressing for Scotland in friendly draws with Poland and Austria, Patterson will make his first Premier League start for Everton against West Ham last weekend having played just 45 minutes for his new club since the 20-year-old in January. moved from Rangers.
Tierney also played in both of his last games for his country before missing against Crystal Palace and club manager Mikel Arteta told Sky Sports on Monday: “He came back from international duty and felt something wrong in his knee.
“There was some damage there. Hopefully we’ll know more on Tuesday, but it’s not looking great.
“He saw a specialist on Tuesday and we will know more about the extent of the injury, but the feeling he is feeling is not very positive and what the scans are showing as well.”
Scotland are expected to face Ukraine in the semifinals which were postponed in early June.
Ukraine’s visit to Hampden Park, originally scheduled for last week, was postponed due to Russia’s invasion of the country.
The winner of that match will face Wales in a one-off match to reach the final in Qatar which starts in November.
While Patterson recently replaced Motherwell’s Stephen O’Donnell as first choice, 24-year-old Tierney is a fixture in Steve Clarke’s side, usually playing on the left side of a back three with captain Andy Robertson of Liverpool at left wing-back. .
