Launceston head coach Mike Lewis has left the National League Two South side by mutual consent after he was offered a different role at the club.
The Cornish All Blacks have lost all nine of their league games this season and sit bottom of the table.
Lewis had previously been forwards coach before becoming head coach during the summer after Neil Bayliss resigned.
"I'd like to thank Mike for all his sterling effort over the past 18 months," said chairman Paul Harrison.
"It's a shame he doesn't want to stay on as a coach I think its because he wants to give his all and I respect him for that.
