FORMER Dunfermline Rugby Club star Murray McCallum has been added to Scotland's Six Nations squad ahead of their second match this weekend.

The 22-year-old prop, who came through the ranks at McKane Park and currently stars for Edinburgh, was called up by head coach Gregor Townsend on Monday in the wake of Saturday's 33-20 victory over Italy at Murrayfield.

He is joined in the pool ahead of the game with reigning champions Ireland by Glasgow Warriors hooker Fraser Brown, whose team-mate Grant Stewart returned to his club.

McCallum, who has won three caps for the senior side, has been drafted in as his Edinburgh team-mate, Willem Nel, continues to recover from a calf strain picked up in the bonus-point success over the Azzurri.

After making his debut in last year's Six Nations as a replacement in Scotland's opening defeat to Wales in Cardiff, McCallum went on to feature against Canada and the USA during the national side's summer tour.

The former Woodmill High School pupil, who recently penned a new two-year contract with European Champions Cup quarter-finalists Edinburgh, could now make his fourth appearance against an Irish side that are ranked second in the world.

Having claimed the Grand Slam 12 months ago, they defeated New Zealand for the first time in November but will tackle Scotland having lost their opening game with England in Dublin.
