Kurt Zouma has pulled out of the West Ham starting line-up just 20 minutes ahead of kick-off and is replaced in the team by Issa Diop.
The centre-back was due to start despite the recent controversy over his attack on his pet cat, however, an injury during the warm-up sees the French defender out of the clash.
Zouma was warming up with his Hammers teammates but during a possession drill the Frenchman walked to one side feeling unwell.
