Just as with the WBBL final, the BBL Play-off Final features the top two sides from the league season as Leicester Riders make their third consecutive appearance against London Lions.
Riders topped the BBL standings to claim their third straight league title while Lions finished as runners-up to secure their highest ever league finish.
Lions are appearing in the Play-off Final for the first time since 2015 while the Leicester side come into the game looking to retain the title they won in last year's season finale.
A victory for Riders will see them complete a league, BBL Trophy and Play-off Final treble for the second year in a row and they booked their place at the O2 with a 166-143 aggregate success over Bristol Flyers.
Meanwhile, the in-form Lions reached the season finale after an impressive display against Glasgow Rocks which saw them pull off their first win in Scotland since 2009 to win their semi-final 169-155 on aggregate.
Sundays showcase comes just a week after Riders coach Rob Paternostro was named Coach of the Year for a fifth time, drawling level with the late and legendary Kevin Cadle and Fab Flournoy MBE.
