JETS' indifferent form continues to plague their season after a magnificent win over London Towers was followed by a shock defeat by bottom side Birmingham Bullets at the weekend.
The contrast in fortunes means Jets still occupy the final play-off berth but with only three points separating seventh and tenth, their fate remains in the balance.
Billy Singleton's men had gone into the match with Bullets high in confidence after a superb third stanza inspired them to clinch an unexpected victory over Robbie Peers' London Towers.
Jets saw off a late fightback by the home side to record a narrow 90-88 win, with Phil Gilbert top scoring with 24 points and Shawn Myers and John Simpson notching 14 apiece.
However, the anticipated play-off charge courtesy of a win against Bullets did not materialise as the visitors produced a sterling defensive display to claim only their seventh win of the entire season.
Jets were slow off the mark and Bullets took a one-point lead at the end of the first period before surging into a 44-37 lead at the interval.
In the penultimate stanza the home side pressed but continued to struggle against a stubborn rearguard.
Jets' frustrations spilled over into the final period as the visitors, inspired by Yorick Williams and Jeff Bonds, cantered to a 96-88 win. nBilly Singleton's side travel to play-off rivals Plymouth Raiders on Saturday in what could be a decisive match.
On Sunday they take on old rivals Newcastle Eagles at the Northgate Arena (5.30pm).
