Top Gear‘s James May and Richard Hammond reportedly turned down an offer to return as presenters on the BBC show without co-host Jeremy Clarkson.

The BBC suspended Clarkson last week after he got into a physical altercation with producer Oisin Tymon, for which Tymon was hospitalized, according to The Daily Record. Clarkson allegedly became angry with Tymon after he was not given a hot meal after a day of filming in North Yorkshire.

The network has launched an investigation into the alleged incident. The series, which tests whether cars live up to their manufacturer’s claims, has been put on hold.

Hammond has been a presenter on the show since its start in 2002, and May joined the next year. May was also a co-presenter on the original Top Gear in 1999.

A petition to reinstate Clarkson has received nearly a million signatures.

The BBC declined to comment for this story.
