Sunday's Women's Premier 15s semi-finals will be shown live back to back in the UK on the BBC Sport website, app and BBC iPlayer.
Defending champions Harlequins and table-toppers Saracens get the action under way as they meet in a repeat of last year's final (14:00 BST).
Having won their first title last May, Quins finished fourth in the table this season to set up a last-four match against Sarries.
Exeter Chiefs will host Bristol Bears in the second of the day's semi-finals (16:30), having beaten the same opposition 29-26 on the final day of the regular season.
Chiefs fought back from four points down to triumph despite the late sending off of prop Laura Delgado for a dangerous tackle.
Delgado and Bristol forward Rownita Marston, who was cited after the game for a dangerous tackle, will both miss Sunday's match.
