Furman joined league leaders Doncaster on loan until the end of the season on Thursday and is out of contract at Boundary Park in the summer.
"Dean wanted to go and, once he sensed the opportunity to join Doncaster, it was hard to turn him down," said Latics chairman Simon Corney on the club's official website.
"Dean has been a great servant to the club, both on and off the field, and a pleasure to deal with."
James Wesolowski is likely to be joined by Jose Baxter in the centre of midfield once more, meaning Chris Iwelumo is favourite to come in for Matt Smith (knee) up front.
Experienced defender Cliff Byrne will miss out once more despite having pain-killing injections to speed up his recovery from ankle ligament damage.
Youssouf M'Changama (knee) has left the club by mutual consent.
