Gordon Strachan has told his men to take no risks with their personal safety when they square up to Qatar in Friday night's international friendly at Easter Road.
Scotland will limber up for the vital Euro 2016 qualifier with Ireland in Dublin by taking on the 2022 World Cup hosts in Edinburgh.
But Strachan is determined not to lose any of his top troops ahead of the Group D clash at the Aviva Stadium on Saturday week which could prove decisive to Scotland’s attempts to reach the finals in France.
He said: “It’s only common sense that if you see something coming that you might [get out of the way].
“I had a radar on me that I could see a tackle coming a mile away – I just hope the players have got the same radar.
“I think the lads will give everything in terms of physical ability. But I really don’t want to see people clattering into each other.
“They have to be sensible. But when you let players go and enjoy a game then you never know. They will go for things. I don’t think I can say to Scott Brown don’t tackle somebody.
“But there might be points during the game when you say that tackle isn’t worth going for.”
The decision to take on Qatar has proved controversial given the plight of migrant workers working country’s World Cup project, with a section of the Tartan Army set to boycott the match in protest
Strachan declined to take questions on the subject as he held his pre-match press conference at the squad’s Mar Hall training base.
But he was happier to discuss the positives of taking on the Asian outfit as his side prepare to cross the Irish Sea.
Six members of his group have not played since the English Championship season ended on May 2nd but the manager insists the Qatar friendly will ensure there is no rustiness when they run out at the Aviva Stadium.
“We’re viewing this game as an extension of our training,” he said. “We have trained twice today, which you normally wouldn’t do before an international game.
“But I can’t treat it as a normal international game with points at stake [against Ireland coming up]. Some of these guys have been off for four weeks and I’ve got to treat [Qatar] as an extension of the training.
“The guys’ condition is fantastic though. I don’t need GPS to see how far they have run. I don’t need heart monitors. I can tell by eye who is fit. The fitness levels are good.”
Sunderland striker Steven Fletcher and Hull left back Andy Robertson both sat out parts of Thursday morning's session after suffering "bumps".
Strachan expects both to shake off their bruises in time to make kick-off in Leith and he is already close to finalising his plans for facing Martin O’Neill’s side.
“It is going to be an intense game,” he said. “You need to be fit to play in this game, you need to have experience to play in it and you need to relish it.
“I don’t have a problem with that last bit, everybody wants to play.
“Am I near the team for Ireland? I’m not too far away. But there is still a chance for someone to blow me away in training and make me think, ‘It’s right for him’.”
He added: “It’s an exciting game for us. The lads are not nervous, they are excited.
“There is adrenalin and excitement. It’s like anybody in top sport. If you ask boxers, I don’t think they are nervous, they are excited. They want to get on with it.
“And you need that. Before the game you might be a bit nervous but that only adds to your focus.”
