Brighton, already without their playmaker Ryan Huntley after he broke a foot last weekend, lost their captain, the England international Yorick Williams, in the third quarter with a twisted ankle.
The Bears seemed to have made the game safe with a 6-0 run, included four free throws from Andrew Alleyne, to lead 85-79. But Shawn Myers inspired the Jets by scoring five of the last eight points, including a three-pointer, plus the game-winning basket.
Sheffield Sharks stayed second, recovering from Thursday night's defeat to Brighton with a 74-64 win at Plymouth Raiders after two three-pointers from Rob Yanders and one from Sterling Davis opened up a 70-60 lead.
London Towers, beaten 109-103 after double overtime at Newcastle Eagles on Friday night, completed a gruelling weekend with an 80-77 victory over Scottish Rocks at Crystal Palace. Niki Arinze secured the win from the foul line after Lamont McIntosh's three-pointer cut Towers' lead to a single point.
Michael New and Joel Burns scored 26 points each to lead Leicester Riders, second from bottom, to their first home win in two months, 99-95 over Thames Valley Tigers.
The bottom club, Birmingham Bullets, whose new signing, Ted Berry, walked out to join a Polish club on Friday, were hammered 109-75 at home by Newcastle.Reuse content
