Sheffield United host Preston on Monday night with the tie balanced at 1-1 after Friday's clash at Deepdale.
Then it is the turn of Reading and Burnley, with the hosts looking to overturn a one-goal deficit.
For Nottingham Forest, a Reading win in the play-offs is the most desirable result as it will see the Royals' parachute payments for next season split between the rest of the division instead.
Already. Birmingham City's £11.2m windfall will be paid out to the other clubs instead after their promotion.
