West Ham United star Andriy Yarmolenko suffered a long-term injury against Tottenham Hotspur at the weekend.

West Ham United co-chairman David Gold has stated on social networking site Twitter that Andriy Yarmolenko will be out of action for six months.

Yarmolenko, who can operate as a forward or as a winger, has undergone surgery to repair a damaged Achilles tendon.

The 28-year-old Ukraine international suffered the injury during West Ham’s 1-0 defeat to London rivals Tottenham Hotspur at home in the Premier League at the weekend.

West Ham co-chairman Gold has stated on Twitter that he will personally convey messages of support to the 28-year-old attacker – who joined the Hammers from German club Borussia Dortmund in the summer transfer window for a fee reported by Sky Sports to be worth £17.5 million – with some fans of the London club responding to his message on the social networking site.

Yarmolenko has made five starts and four substitute appearances in the Premier League for West Ham so far this season, scoring two goals in the process, according to WhoScored.
