Betting website 888poker has dropped Luis Suarez as its ambassador following his bite on Italy's Giorgio Chiellini at the World Cup during his side's 1-0 win.
The striker was banned for nine international games and from all football for four months after being found guilty of biting an opponent for the third time.
A statement on 888poker.com read: "888poker signed Luis Suarez following a fantastic season for which his achievements were widely recognised."
"Regrettably, following his actions during Uruguay's World Cup match against Italy on Tuesday, 888poker has decided to terminate its relationship with Luis Suarez with immediate effect."
Suarez only joined the online gambling company as a worldwide ambassador just before the World Cup, and plans had been made for him to attend several of their promotional events in the coming months.
Suarez's boot deal with Adidas could also be in jeopardy after the sportswear manufacturer announced on Thursday that it too would consider its partnership with the 27-year-old.
Suarez was last year banned for 10 games in domestic competition after biting Chelsea defender Branislav Ivanovic while playing for Liverpool, and in 2010 when with Ajax, he served a seven-game ban after biting PSV Eindhoven's Otman Bakkal.
Following the Ivanovic incident, Adidas stated "We will be reminding him of the standards we expect from our players", and it came down in support of football's governing body after the latest controversy."
A statement on Thursday read: "Adidas fully supports FIFA's decision. Adidas certainly does not condone Luis Suarez's recent behaviour and we will again be reminding him of the high standards we expect from our players."
"We have no plan to use Suarez for any additional marketing activities during the 2014 FIFA World Cup. We will discuss all aspects of our future partnership directly with Suarez and his team following the World Cup."
Suarez's future at Liverpool has also been widely speculated, with Spanish side Barcelona believed to be interested in signing the striker regardless of his ban.
