Swindon will then travel to Brighton's on Thursday 20 May with a 7.45pm kick off.
Tickets will go on sale for season tickets holders for the home leg on Monday 10th May, and for away tickets they are expected to go on sale to season tickets holders only on Wednesday.
As the away end at Brighton only holds 700 it's expected that no tickets will go on general sale as season ticket holders will buy the lot.
