Winston Reid has been hit by another injury setback that plunges his West Ham career into fresh doubt, Football Insider can reveal.

The centre-back, 31, has not played since March of last year after breaking down with a knee injury that required surgery and was followed by a series of other issues.

A West Ham source has told Football Insider that Reid had been pencilled in by the coaching staff to make his comeback as an over-age player for the club’s Under-21s against Cheltenham Town last night.

But the defender has been suffering fresh back and knee pain, and his return has been put on hold for many more weeks in another shattering blow for him.

Hammers’ medical staff believe Reid should not be risked as there is the potential he could break down with an even more serious injury that would sideline him for a lengthy time.

This comes after Manuel Pellegrini revealed last week that the New Zealand international was on the comeback trail as he prepared to gradually ease him back into action.

The Chilean manager explained Reid would start off playing for the development squad to get fully fit before being promoted to the senior team.

West Ham’s first choice centre-back pair this season have been Issa Diop and Angelo Ogbonna, with Fabian Balbuena providing cover and competition from the bench.

Reid joined West Ham from Danish club FC Midtjylland in the summer of 2010 for around £4million and has made 223 appearances for the club.

In other West Ham news, it can be REVEALED that the club are ready to sell in-form player for £5million in January.
