A case of the dengue fever – no joke – has knocked John Lineker from Sunday’s bout at UFC Fight Night 83 with Cody Garbrandt.

So far, there has been no word if the promotion will be able to secure a replacement on short notice to keep Garbrandt (7-0) on the Pittsburgh card.

Lineker (26-7), who has battled weight-cutting issues, confirmed the news on social media Monday.

The bantamweight bout was scheduled to be part of the FOX Sports 1 main card that features Donald Cerrone vs. Alex Oliveira.
