Young midfielder Chris Cohen has extended his loan spell at League One side Yeovil Town until the end of the season.
The 18-year-old originally headed to Huish Park on a one-month loan in November. After extending the deal by a further month, he has now agreed to sign for the remainder of the campaign.
Chris, who has played once for Hammers this season, in the Carling Cup second round win over Sheffield Wednesday, has already made 12 appearances for Yeovil, who currently lie 10th in League One.
