The game is going to be pivotal in the fight to survive in the Premier League and Latics supporters have reacted in the best way possible by selling out their allocation.
"It's no surprise to me because the fans have been great all season," said manager Roberto Martinez.
He continued: "It will be a crucial game and we need our fans to continue to do what they have done all year and create an atmosphere that everybody can enjoy and be proud of."
The Latics have requested more tickets from Blackburn but are unlikely to be allowed and further allocation.
