Following their early exit from the ICC Champions trophy in England, the players were expected to resume training at the nets on Tuesday for the three-day match against Namibia which starts on Friday at the Nairobi Gymkhana club.
But most of the senior players including Steve Tikolo, who announced he had stepped down as the national team skipper, said on Wednesday they would not play unless their contracts were renewed.
The Kenya Cricket Association (KCA) had offered to extend their contracts, which expire on September 30 for another two months while a new sponsor was found.
Team manager Ramesh Bhalla said they were disappointed with the stance taken by the players.
"The KCA is very firm on this. We are in the process of selecting a new team altogether. The players should realise they performed very poorly in England," he said.
