Nottingham Panthers coach Corey Neilson says he shoulders the responsibility for his side's heavy defeat at fierce rivals Sheffield on Thursday night.
Panthers, who beat the Steelers 3-2 on Boxing Day, were hammered 9-4.
Neilson told the Panthers website: "We lost our composure at times. We got down 5-1 and then went to a more aggressive system.
"That totally backfired, so I hold my hands up. I dug us into a huge hole, an embarrassing hole."
Panthers have a four-point lead at the top of the Elite League table, but second-placed Belfast have two games in hand.
"The guys are all down and disappointed," added Neilson. "We know we let the fans down against Sheffield, but we pick ourselves up against Dundee on Saturday.
"Take nothing away from Sheffield, they played really well at times. Sheffield were very good on the night and deserved the victory."
Meanwhile, forward Kelsey Wilson will be suspended for three matches after a five-game ban for slashing was downgraded by an Elite League disciplinary committee.
Wilson will miss Panthers' home game with Dundee Stars on Saturday, followed by back-to-back clashes with Coventry Blaze the following weekend.
