Belfast Giants were hammered in Sunday's Elite League title clash with leaders Nottingham Panthers in England.
The champions led at the end of the first period through Adam Keefe's goal but the Panthers hit back in style.
Bruce Graham, David Ling, Eric Werner and Brandon Benedict struck in the second period before Jason Beckett and Matthew Myers completed the rout.
The defeat at the National Ice Centre leaves the Giants four points behind Nottingham but with a game in hand.
Belfast started the weekend with a 4-1 victory over the Cardiff Devils at the Odyssey on Friday night.
Andrew Fournier, Jeff Mason, Mark Garside and Scott Champagne netted for the hosts.
The Giants are back in action on Monday night, away against Hull Stingrays in the first leg of their Challenge Cup quarter-final.
