Celtic handed chance to seal SPL title in front of own fans after post-split fixtures are announced Butcher's squad will round off their season with a Highland derby clash as they travel to Ross County on May 19. In the bottom six, Dundee - 13 points behind St Mirren at the foot of the table - could be relegated in Paisley a week on Saturday if they lose to the Buddies. The last Edinburgh derby of the season is scheduled for May 12, as Hibs travel to Hearts, while the final round of matches in the bottom six will take place on May 18. Dunfermline have been docked 15 points for going into interim administration. The Scottish Football League enforced the immediate points deduction following a board meeting today. The penalty puts the Irn-Bru First Division side into ninth place, below Cowdenbeath in the relegation play-off spot. The SFL also imposed a transfer embargo which prohibits the club signing players aged over 21 until they come out of administration. Dunfermline will also be subject to a further 10-point penalty and be required to pay a £150,000 guarantee if they do not secure a Company Voluntary Arrangement by the start of next season. Dunfermline are now eight points above bottom club Airdrie and two behind Cowdenbeath on 27 points, with five games to go until the end of the season. Partick Thistle defender Aaron Muirhead has been issued with a notice of complaint by the Scottish Football Association's compliance officer Vincent Lunny following his red card against Queen of the South in Sunday's Ramsdens Cup final defeat. The 22-year-old was sent off for head-butting Doonhamer captain Chris Higgins after he and his team-mates celebrated in the face of the Jags player after he had a late penalty kick saved.
