Programme bosses have announced Doug will return to the village as a regular character in the run up to daughter Laurel's wedding to Marlon.
However they have also hinted that providing moral support for his daughter's impending nuptials may not be the only reason for his return.
Meanwhile, The Woolpack's landlady Diane Sugden will be intrigued by Doug's return which could possibly stir up some old feelings for the pair.
This will be especially true as Doug's new way of earning money could mean Diane will see him in a new light.
Speaking about his return to the soap, Duncan said: "It is lovely to be back in Yorkshire as part of the Emmerdale family.
"It feels like I have come home and I'm really excited about what is ahead for Doug".
Doug Potts was last seen in the village in 2011 before he left to rekindle life with his ex-wife Hilary.
Viewers will see the character's return on 9 September.
