Hearts' Lee Wallace a doubt for Scotland's Euro games
Wallace played in Scotland's recent defeat to Sweden
Hearts' Lee Wallace is a major doubt for Scotland's Euro 2012 qualifiers against Lithuania and Liechtenstein due to bruising on a bone in his ankle.
Wallace passed a fitness test to play against Dundee United on Sunday but pulled up in the warm-up and ended up missing the 1-1 draw.
Hearts boss Jim Jefferies said: "We tried an injection and then he went out for the warm-up, but it hadn't numbed.
"It's too early to say. He'll go tomorrow and he'll get assessed."
The defender was expected to play at left-back in Scotland's opening Group I match in Kaunas on Friday and the subsequent home match against Liechtenstein on Tuesday.
But now national manager Craig Levein may have to consider other options.
"If he's not playing, he's got a couple of weeks to get it sorted out, but it was too sore," Jefferies told BBC Scotland.
"He aggravated it in the Elgin game, we took him off and he didn't really recover.
"We got it scanned, there's nothing other than deep-rooted bruising."
Meanwhile, Jefferies was unhappy with some of referee Craig Thomson's decisions made in his side's draw with United.
It feels like a defeat. It's just disappointing that we've dropped four points in the two home games

Hearts led 1-0 through David Templeton's first-half strike and the visitors were given the chance to level with a penalty on 75 minutes after Ismael Bouzid was adjudged to have handled in the box.
Jon Daly missed the spot-kick, but Morgaro Gomis did find the net with a stunning strike five minutes from time.
"We thought it was a terrible decision for the penalty and justice was done when it was a great save, but I don't think you can legislate for the equaliser because it's goal of the season stuff. It was a fantastic goal," said Jefferies.
"They then took the attitude that they could go and win it. And I'm glad they got a goal because I think Craig Thomson would've played here all night until they scored.
"For both teams, I thought there were some strange decisions out there today.
"(Hearts player) Craig Thomson put in a fantastic challenge on Craig Conway. He won the ball, he won it cleanly and they got a free-kick.
"Are we just going to sit and accept that? That could've been played into the back post and it's a good job they didn't score, I might have been on the pitch myself.
"It's these things that frustrate you. Get it right. If it's a foul, it's a foul. Dundee United in the first half had Conway scythed down. I was giving my players pelters for diving in, but they didn't get a free-kick for it.
"It's still a competitive game. It's about knowing what a foul is and what a foul isn't. They've got to find some consistency."
Hearts remain unbeaten for the season going into the two-week international break.
"It feels like a defeat, but we're undefeated this season and I think teams will find that Hearts are more than useful this season and we want to keep that going and it's a long season," added the Hearts manager.
"It's just disappointing that we've dropped four points in the two home games, but that's how tough and how tight this league can be."
