Fans can pay on the day at ForestNottingham Forest have relaxed the all-ticket ruling for Saturday's FA Cup with Budweiser, third-round tie against Latics.
Latics' fans will be able to pay on the day at the City Ground.
They are still advised to buy tickets before travelling to prevent queuing on the day.
As Forest have no cash turnstiles, tickets will have to be purchased from the away ticket booth at the back of the Brian Clough Stand.
Tickets will be on sale at Boundary Park until 3.30pm tomorrow (Friday).
Forest advise Latics' season-ticket holders that they will not be entitled to discounted prices on the day which will be £12 for adults and senior citizens and £6 for under-16's.
Latics have sold over half of their allocation of 4,000 tickets.
