Wigan have again cut ticket prices as they bid to boost attendances at the JJB Stadium.
Jewell has been frustrated by low attendances
Tickets for the Chelsea game were £15, sparking a virtual sell-out, but attendance dropped dramatically for the next match, which was full-price.
The club have now responded by dropping prices for another seven games.
"We need the fans to be our 12th man," said manager Paul Jewell. "These are crucial times. I hope the supporters will join us for the battle."
Wigan were unlucky to lose to a last-gasp Arjen Robben goal against Chelsea but it was their third home defeat in a row and they have since made that four with a disappointing 3-0 loss against Blackburn.
That form has dragged Jewell's side into a relegation battle and the manager added: "Everyone saw what a fantastic atmosphere we generated with a packed JJB Stadium against Chelsea.
"It was absolutely rocking and it had a big impact on the performance of the players.
"The lads were buzzing in the dressing room to be playing in front of a noisy and passionate full house and we want to try and re-create that from now until the end of the season."
The JJB Stadium was 2,900 short of the 25,000 capacity for the Chelsea game but only 14,864 attended the match against Blackburn on New Year's Day.
Earlier this season some tickets had cost £35 for category A games and £30 and £25 for other matches.
