The future of Magnus Racing is up in the air, with the John Potter-owned team to potentially cease operations following the conclusion of the IMSA WeatherTech SportsCar Championship season.

The longtime sports car racing squad, which has won multiple North American Endurance Cup titles, is understood to be preparing to pull out of full-time competition, with sources confirming to Sportscar365 that a return in 2020 is currently unlikely.

However, it’s believed a program around the Michelin Endurance Cup-only races could still be an option for next year, although it’s unclear if it could be with the Bronze-rated Potter, who is rumored to be retiring from driving.

When reached by Sportscar365 a team representative denied claims of the team ceasing operations and declined to provide any additional comment.

Founded in 2010 by Potter, Magnus has been a mainstay in IMSA GT competition for the last decade, having fielded Porsches, Audis and most recently a switch to a Lamborghini Huracan GT3 Evo for this year.

Potter and longtime co-driver Andy Lally have only one podium finish to their credit this year, coming at the Mobil 1 Twelve Hours of Sebring, in what’s considered to have been one of the most competitive GT Daytona class seasons to date.

It’s understood Lally’s contract with the team expires at the end of this year.

Should Potter exit the sport, it would be the second gentleman driver to leave the IMSA GTD ranks following Ben Keating’s decision to shift his focus to the FIA World Endurance Championship with Team Project 1.
