Hearts goalkeeper Mark Ridgers is waiting on results of a knee scan after a collision forced him off during the Scotland Under-21 international against Belgium.
Ridgers, 22, came off worst from a challenge with Belgian Thomas Meunier in the first half of the match.
The Tynecastle number two was stretchered off the park and took a scan on Wednesday to discover the extent of the damage.
There are fears Ridgers could have damaged ligaments in the clash, and he is wearing a brace on the knee in the meantime.
The goalie, who has spent loan spells with East Fife and Airdrie, Tweeted to tell he was staying positive.
Ridgers wrote: “Fingers crossed, hoping it’s not what we think.
“Thanks for all the nice messages. Will let everyone know once I find out.”
Club boss John McGlynn told the official Hearts website: “The plan is to have Mark scanned on Wednesday and then we’ll see what the situation is.”
