Old Firm: Craig Thomson to referee final derby of the season
Craig Thomson will referee Sunday's final Old Firm derby of the season at Celtic Park.
Celtic, who have clinched the Scottish Premier League title, go into the game 18 points ahead of their rivals.
Ally McCoist's side won the last derby, a 3-2 win at Ibrox on 25 March, that prevented Celtic from clinching the title that day.
Thomson was in charge for the derby at Ibrox last September, when the hosts won 4-2.
Celtic emerged victors the last time the sides met at Celtic Park in December, Joe Ledley heading the only goal of the game.
