Jackie McNamara, the Wolverhampton Wanderers defenderfears that he might never play in another major finals if Walter Smith's men fail to reach next year's World Cup.
McNamara will be 32 only 12 days after their final qualifying match in Slovenia and says that that might well be his farewell on the big stage if results go against Scotland.
McNamara, who left Celtic on a free transfer in the summer, will discuss his future with Smith but fears his international career is drawing to an end.
He said: "I would have thought this is my last chance of playing in the World Cup and even at the European Championships.
"I will have to speak to the manager about it but it's not right to hang about beyond a certain stage. I want to play on but the most important thing is the team.
"There are a lot of young players coming through and you have to give them a chance of getting experience."
McNamara said that hearing of Norway's late winner in Slovenia was a real sickener as his team-mates enjoyed a post-match meal after the weekend draw with Italy at Hampden Park.
But he is convinced the dream is still on and that they can shock the Norwegians in the Ullevaal Stadium tonight.
He said: "We heard about the Norway goal as we were eating on Saturday so that was hard to take.
"We rode our luck a bit at times in the Italian game, especially when Christian Vieri missed that chance after one of our mistakes. But we are hoping to get the victory and we are still hanging on in there. I always think we can do well and we are capable of beating Norway."
Smith knows Scotland have to win all their remaining three group matches. Second-placed Norway are five points above them and the odds are stacked against Scotland.
