Posta Rangers will play Ulinzi Stars in the Kenyan Premier League (KPL) match on Sunday without the services of the two key players.
The Mailmen will have to do without the services of captain Simon Mbugua and Charles Odette. The two have been vital for the Sammy Omollo-led charges this season but their stay is under jeopardy.
"Everyone else is available for the game apart from Odette and Mbugua whose contracts have expired," Omollo told Goal on Sunday.
