Foxsports.com.au understands that the fictional and bespectacled wizard will continue to ply his sporting trade in the Quidditch arena.
But Potter, the very real Sydney University try-scoring sensation, is moving back to Melbourne to push for a Super Rugby debut in 2020.
The magical winger dominated the Shute Shield where he led the competition in defenders beaten (117), clean line breaks (45) and total metres (1446).

“But it’s nothing I haven’t heard before so it’s easy to laugh it off,” Potter said.
“I’ve seen all the movies but haven’t read any of the books, which is quite disappointing for a lot of people because they make jokes I don’t understand.”
The contract caps a dream week for Potter after helping Uni to their second consecutive Shute Shield premiership on Saturday.
“I couldn’t be happier to be returning to Melbourne,” Potter said.
“My first representative honours came with an underage Victorian state team, so to now get the chance to return to Melbourne and to work hard for the opportunity to play at the Stockade makes my journey feel like it has come full circle.

“This really does cap off a life changing weekend,” Potter said.
“My time in Sydney has been great for my rugby development but Melbourne is home.
“The Rebels have always been my team growing up, and now I want to contribute to the future of the club and take my rugby to another level.”
Rebels GM of Rugby and Pathways, Nick Ryan, was pleased to see the Melbourne-raised outside back return.
“Harry was always spoken of highly by our pathway coaches here in Victoria when he was coming through the youth programs,” Ryan said.
“We are genuine in wanting to build a local pathway and it’s always pleasing when a player chooses to come back to Melbourne to pursue their rugby ambition.
“It’s only by building a world class program that you can capture the best talent.
“Along with guys like Jordan Uelese, Rob Leota, Trevor Hosea, Pone Fa’amausili and Fereti Sa’aga, we’re beginning to really show that there are opportunities here for young and hungry Victorian players.
“The NRC is a big stage for other prospects to show us if they are ready for the leap to Super Rugby.’
“Harry will be surrounded by experienced and talented outside backs and we are committed to taking his game to another level.”
The Rebels also signed former Australian sevens player Boyd Killingworth on Wednesday.
