Online gambling firm 888poker have terminated their relationship with Luis Suarez with immediate effect after he was suspended from football for four months for biting an opposition player.
"888poker signed Luis Suarez following a fantastic season for which his achievements were widely recognised," a statement said.
"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."
Adidas, who also used Suarez in their World Cup advertising campaign, said they fully supported Fifa's sanctions and would be discussing further aspects of their partnership with the Uruguayan striker after the World Cup.
If upheld, the four-month Luis Suarez ban from football would see him miss 16 matches, including nine Premier League games.
