Andy Carroll is a slight doubt for West Ham's trip to Middlesbrough - with a whiplash injury.
The striker scored with a spectacular, acrobatic scissor kick during last week's 3-0 win over Crystal Palace.
But at the end of the match he was feeling a problem with his neck and had to sit out training earlier this week.
Manager Slaven Bilic was surprised by the unusual diagnosis, but still expects his big frontman to be fit for the trip to Teesside.
