Thomson was due to face Gilbert Burns, but will be unable to take his place on the card. It is not yet clear what this means for Burns.
The injury is a blow to Thomson who is coming off consecutive defeats to Bobby Green and Ben Henderson.
The Fight Night card has already undergone major changes, with the orignial headline fight between Urijah Faber and Raphael Assuncao cancelled as a result of an ankle injury suffered by Assuncao.
As a result, the welterweight bout between Demian Maia and Ryan LaFlare became the co-headline event along with the now abandoned fight between Thomson and Burns.
