The decision was retaliation for a public protest against unpaid salaries last week during the HSBC World Rugby Sevens Series in Paris, when national team players hid the 'Brand Kenya' logo on their shirts.
The sponsorship withdrawal has thrown the cash-strapped Kenya Rugby Union (KRU) into disarray with head coach, Innocent Simiyu being sacked and top officials going into a crisis meeting Friday to seek a new sponsor ahead of next month's World Cup.
Simiyu said it has been "a great honour" to coach Kenya's sevens team.
