Porsche withdraws works IMSA Mid-Ohio entries after COVID-19 positives

The decision follows the Weissach marque withdrawing the works drivers that raced at Le Mans 24 Hours from this weekend's Nurburgring 24 Hours in the wake of a series of positive COVID-19 tests during routine checks.

Of Porsche's four IMSA GTLM drivers, three - Nick Tandy, Frederic Makowiecki and Laurens Vanthoor - were present at Le Mans, and their last-minute withdrawal makes it impossible for the pair of CORE Autosport-run 911 RSR-19s to race at Mid-Ohio.

It leaves just Corvette Racing's two C8.Rs and BMW's pair of Rahal Letterman Lanigan-operated M8 GTEs in the GTLM grid this weekend.

"Based on yesterday's decision that no employee or racing driver of our Le Mans team will participate in the Nurburgring 24 Hours, we have today decided that this ruling will also apply to the upcoming IWSC race in Mid-Ohio," said Porsche's vice-president of motorsport Fritz Enzinger.

"This means that Laurens, Nick and Fred [will not] be travelling to the USA.

"This is very regrettable, but we would like to emphasise that in this case as well the health of all those concerned is the prime focus of the decisions we have taken."

Earl Bamber is the only one of the Porsche IMSA GTLM quartet who wasn't at Le Mans and was therefore clear to drive at Mid-Ohio, but the New Zealander has been reassigned to Porsche customer squad KCMG for the Nurburgring 24 Hours.

Bamber will join Jorg Bergmeister, Timo Bernhard and Dennis Olsen at the wheel of one of KCMG's two Porsche 911 GT3 Rs in the German race, with Richard Lietz, Romain Dumas and Patrick Pilet all having been forced to stand down.

KCMG's second car will be driven by Olsen - who pulls double-duty - Alexandre Imperatori, Josh Burdon and Edoardo Liberati.

Porsche also withdrew the Manthey Racing squad from the Nurburgring race, while the Falken line-ups have been revised having been unable to use Matteo Cairoli and Thomas Preining.

Christian Engelhart and Dirk Werner will drive the #33 Falken entry, and Peter Dumbreck and Martin Ragginger will take the #44 car - while Sven Muller and Klaus Bachler will double-duty for both entries.
