Hugo Southwell has been ruled out for up to three months after dislocating his shoulder during the first half of Scotlands 19-18 defeat to Ireland at Murrayfield on Saturday,

Lamont did well when he replaced Southwell for the second half of the Ireland match, and after a series of impressive performances for Glasgow Warriors this season the 24-year-old has forced his way back into contention for a first international start since the autumn of 2005.

Then he played on the right wing against Samoa, but was forced to leave the pitch before the break with concussion.

Lamont, asked about his 40-minute stint at the weekend, said: I was obviously delighted to get half a game - Ive had to wait a long time to get significant match time like that.

But it was absolutely heartbreaking to lose. I was pretty confident with 15 minutes left in the game that we could hold on, and go on to win it.

But as Frank [Hadden, Scotlands head coach] has already said, we didnt execute things properly and it ended up costing us the game.

Overall I was pleased with the way I played. It wasnt perfect but I was pretty happy with the impact I made.

There were a couple of mistakes Ive got to tidy up, but I felt I ran the ball back pretty hard and caused them a few problems.

Whether thats enough for Frank to start my at fifteen on Saturday is another question.

While Lamont says he would like to be considered primarily as a full-back, Hadden has made it clear within the last month that he regards the player more as a winger.

Lamont is hoping that he will be given the opportunity of Saturday to prove that he has got what it takes to play in his preferred position at international level.

He said: Ive read about him not seeing me as a polished 15  I think those were his words were  but Ive just got to try to prove him wrong. Ive got try to show him that I can play 15.

Obviously international level is a step up from club rugby, but I feel Ive been doing a good job at Glasgow in that position, and now its just a case of trying to prove to Frank that I can do it at international level.
