Sussex Sharks will play either Nottinghamshire Outlaws or Somerset in their Vitality Blast semi-final at Edgbaston on Saturday 15th September.
The winner of that match will then play either Lancashire Lightning or Worcestershire Rapids in the final later on the same day.
The semi-final draw was made on Sunday afternoon following the postponment of the Somerset v Nottinghamshire Outlaws quarter-final at Taunton. That match will now be played at 1pm on Monday.
The order of the two semi-finals will be determined following the conclusion of this last remaining quarter-final.
Ticket information for Sussex Sharks supporters hoping to attend Finals Day will be released on Monday.
