A sudden case of Dengue fever has forced John Lineker to pull out of his bout against Cody Garbrandt on February 21, as Portal do Vale Tudo reported.

The Brazilian government has been strongly campaigning for people to protect themselves from the mosquito which carries the disease and two others (The Zika virus and Chikungunya virus) as an epydemy has been going on in the country since last year.

The bout would also mark Lineker's second bantamweight bout after a 6-2 run in the UFC's flyweight division which ended after Lineker was forced to move up to 135 when he missed weight for the fourth time. He returned last September in a "Fight Of The Night" one-round barnburner against Francisco Rivera, which he won by submission.

So far, no replacements have been announced for Garbrandt, who was supposed to fight Lineker at UFC Fight Night 83, on February 21, in Pittsburgh, Pennsyilvania. The card will be headlined by lightweights Donald Cerrone and Alex Oliveira.

UPDATE: Lineker has since confirmed his withdrawal from the bout on Twitter.
