WIGAN's plans for this tough test have been disrupted by Colin Lee's departure from the JJB Stadium.
Lee has been appointed Walsall's new manager after just a month at Wigan working as coach, and club bosses say he will be missed.
Welsh international striker Simon Haworth could start at the Britannia stadium alongside Andy Liddell.
Manager Paul Jewell wants a return to winning ways and hopes Wigan improve on a dismissal midweek showing against leaders Reading.
Positional changes are likely but Lee Ashcroft is still out with a shoulder injury.
Last season: Stoke 2 Wigan 0.
Key opponent: James O'Connor, a talented player who's is in fine form.
