Plymouth Raiders threw away a 14-point lead to lose 83-80 to BBL Championship leaders Leicester Riders.
The Raiders had led 40-26 just before half-time and were still 59-57 up at the end of the third quarter.
Riders came back thanks to GB skipper Drew Sullivan and Yorick Williams, who scored 20 and 12 points respectively while Jeremy Bell hit 25 for Plymouth.
But Plymouth made up for it on Sunday as they crushed Durham Wildcats 113-68 in Newton Aycliffe.
Jeremy Bell again top-scored for Plymouth with 27 points while Colin O'Reilly and Mike Ojo scored 22 each.
