Celtic faced Delting in an absolute thriller at Seafield with the home side grabbing all three points in a result that puts them right back in the hunt for the league.
It was the second time the two sides had faced each other in a week and similarly to the previous fixture, it was the hoops that dominated the opening period and were passing the ball around well on the slick albeit soft Seafield surface.
After 20 minutes or so, having tested Matthew Saunders on a couple of occasions, Celtic finally got their break-through when Kennedy Moar's cross was turned home by Connor Regan.
The home side made it 2-0 moments later when a short corner was played to Ryan Grant, who curled in a delightful cross which was perfectly met by Saul Sim and the young midfielder glanced the ball into the far corner.
Celtic then had chances to extend their lead however James Aitken's shot was deflected inches wide and Saunders again spread himself well to save from Brendan Johnson.
Just 5 minutes before half time, Delting found a way back into the game. Glaser in the Celtic goal was caught off his line and the wily Leighton Flaws looped the ball into the far corner to make the score 2-1 going into the break.
Having got back into the game just before half time, Delting were level just after when Glaser did not deal with a ball in from the left wing and Craig Johnson was at hand to tap the ball into the empty net for 2-2.
Not to be deterred, Celtic went up the other end minutes later to regain the lead when Aitken cut back for Regan to tap home his second and Celtic's third.
However Delting were not giving up there and again equalised in controversial fashion. A fairly innocuous kick out from Glaser was deemed illegal with the young keeper somehow adjudged to have gone out his area and Flaws bent home the resulting freekick.
Celtic threw on 16-year old Shay Regan in an attempt to freshen up the attack, and the substitution almost paid dividends with the winger almost scoring with his very first touch but again Saunders was there.
Tom Moncrieff and Robert Smith were unlucky not to receive penalties and Connor Regan was again thwarted by an excellent save from Saunders to keep the score all-square.
With the end-to-end match somehow playing out for a draw, Celtic managed to conjure up one final attack and Joel Bradley knocked the ball in off the bar after a bit of pinball in the box following a corner.
Youngster Shay Regan did deservedly get his name on the score-sheet in the dying seconds, slotting home a Tom Moncrieff cross in injury time.
In a very exciting game for the neutral, Saunders shone for Delting while Saul Sim and Joel Bradley had really good games for the home side.
