Heurelho Gomes has joined our injured list ahead of Sunday's trip to West Ham.
A scan on Thursday revealed the goalkeeper had sustained a groin injury during Wednesday victory at Hull, which will keep him out of the London derby.
Michael Dawson and Jermaine Jenas have also undergone scans on their injuries.
Defender Michael's Achilles problem is healing well and he is now in the strengthening phase of rehab, while JJ is now undergoing rehab on a sprained calf muscle.
Jonathan Woodgate, meanwhile, is progressing well following groin surgery, and Gareth Bale is building up his fitness before returning to full training following his summer knee operation.
Ledley King could return against The Hammers having sat out Wednesday's trip to the KC Stadium.
