A goal towards the end of the second period proved enough for Nottingham to beat Edinburgh 2-1 and hold on to second place in the Elite League.
Both sides found the net within the first seven minutes of play, with Jeff Marshall putting the home side ahead before Joe Cardarelli equalised.
In the 38th minute Curtis Bowen scored and a goalless third period meant this was enough to secure the points.
Nottingham are now eight points behind Belfast, having played six games fewer.
Newcastle goalkeeper Trevor Koenig was in fine form, with a 34-shot shut-out in their 4-0 win over Basingstoke.
David Longstaff gave them a first minute lead, doubled by Jonathan Weaver on a power play.
Matt Beveridge and Andre Payette added further scores before the home side belatedly changed their net minder, and there was no further scoring.
Over 4,000 fans were at the Belfast Arena to see the Giants maintain their lead at the top of the table after a 2-0 win over London.
Goals by Shawn Skiehar and Courtenay were enough to wrap up the points, as Belfast managed 36 shots on goal as opposed to 22 by London.
Three goals in 90 seconds in the first period, all set up by Vezio Sacratini and scored by Jonathan Phillips, put Cardiff on their way to a 4-2 win over Coventry.
Barrie Moore pulled one back for Coventry just before the first period ended, with Ashley Tait adding a second on a power play.
But Gerard Adams' late goal rounded off a comfortable win for the Devils.
