Injury hit Sheffield Steelers found their winning touch again tonight.
Without Robert Dowd, Colton Fretter and Mike Duco at Nottingham's NIC Arena, coach Paul Thompson had to come up with something dramatic.
He did: putting assistant coach Darrell Hay into the line up for the first tine and converting Cullen Eddy and Rod Sarich into wingers.
Steelers went into the 'derby' game with Panthers on the back of two consecutive defeats, having slipped up at home to Edinburgh Capitals on top of a 5-1 mauling at Cardiff Devils.
Their last win had come a week ago over Panthers, at Sheffield Arena
It was Nottingham who went ahead in this Challenge Cup Group game, Stephen Schultz netting on the Power Play.
Mathieu Roy levelled and an exquisite goal from Sarich put Sheffield ahead.
Nottingham equalised in the final period,through Bryan Schmidt, but former Panthers favourite Chris Lawrence silenced the home boo boys with the winner.
Elsewhere Cardiff Devils gained revenge on Belfast Giants by securing a 3-2 win in Northern Ireland to open up a two-point lead at the top of the Elite League table.
The Giants came from behind three times to beat the Devils 4-3 after overtime on Friday but were on the wrong end of another close-fought encounter on Saturday.
Trevor Hendrikx opened the scoring for the Devils in the first period and Joey Martin doubled the lead on the power play in the second before the Giants finally broke through five minutes into third period thanks to James Desmarais.
Jake Morissette restored the Devils' two-goal advantage two minutes later and although Brandon Benedict finished an impressive play from the Giants to make it 3-2, the Welsh side held out in a thrilling finale.
Manchester Giants secured their second regulation win of the season with a 6-4 success at Coventry Blaze, who went down to a fourth defeat.
David Phillips cancelled out Russell Cowley's first-period opener for the Blaze early in the second before a double from Ross Venus sandwiched Matty Davies' effort for the visitors to leave the home side 3-2 ahead at the end of the second period.
But Storm hit three times without reply in the third period through Patrik Valcak, Grant Toulmin and Vinny Scarsella and although Ashley Tait pulled one back for the Blaze, Toulmin completed the scoring.
Bobby Chaumont, Riley Wetmore, John Dolan and Lou Dickenson were on target for Dundee Stars in their 4-1 win at Fyfe Flyers, who replied through Ryan Dingle.
