West Ham striker Diafra Sakho is out for the remainder of the season after tearing a thigh muscle on Saturday against Stoke City. The 25-year-old is West Ham's runaway top scorer this season with 12 goals and was forced off after 59 minutes during their 1-1 draw at home. West Ham claimed Sakho could return 'before the end of the season' on their official website, but it appears unlikely the Senegal international will be fit enough to feature before the next campaign. West Ham striker Diafra Sakho limps off against Stoke City after 59 minutes to be replaced by Carlton Cole . The West Ham striker has scored 12 goals this season but is set to miss the rest of the campaign . Ten of Sakho's 12 goals came in the Barclays Premier League, with Andy Carroll and Stewart Downing the club's next top scorers with just five apiece. It comes as a blow for manager Sam Allardyce who is aiming to finish in eighth position as he fights for a new contract with West Ham. Allardyce's current deal expires at the end of the season and it is not certain co-owners David Gold and David Sullivan will keep him on, despite already beating last season's total by three points.
