London: West Ham United`s Ivory Coast international Guy Demel was released from hospital on Sunday after suffering a head injury during his side`s 2-0 Premier League win at Cardiff City, the club said on Twitter.
The 32-year-old defender was carried away on a stretcher after receiving oxygen on the pitch, having fallen heavily following a collision with Hammers team mate Roger Johnson on Saturday.
He suffered concussion and a damaged shoulder and was unconscious for several minutes before spending the night in hospital in Cardiff.
British media reported he had suffered neck and shoulder injuries, adding to West Ham`s already considerable injury list.
The victory took West Ham out of the relegation zone into 17th position, one place above Cardiff.
