Kubica will replace Jan Magnussen for the final two rounds of the season at the Bahrain International Circuit. 

The Pole will partner Anders Fjordbach and Dennis Andersen for High Class Racing.

He made his LMP2 debut with the team back in January at the Daytona 24 hours round of the IMSA SportsCar Championship, where the team retired due to a gearbox issue.

Kubica will contest in the six and eight-hour races in Bahrain on October 30 and November 6.

“After the ELMS Championship and of course participation at Le Mans, I’m happy to join High Class Racing for the last two rounds of the WEC in Bahrain,” Kubica said.“Of course I know the team and my teammates Anders and Dennis… We’ll try to enjoy and achieve as strong a result as possible in those two rounds.”

“I’m looking forward to rejoining the team again for the second time this year and let’s hope to achieve some good racing in the ProAm class.”

The former BMW and Renault F1 driver deputised for Kimi Raikkonen at the Dutch and Italian Grands Prix earlier this year after the Finn tested positive for COVID-19.

Kubica is unlikely to be in the frame for the second Alfa Romeo seat for next year alongside Valtteri Bottas.

Chinese star Guanyu Zhou and current F2 points leader Oscar Piastri are the leading contenders.
