According to The Telegraph, West Ham defender James Tomkins could miss the rest of the season after suffering a dislocated shoulder.
The 25-year-old has been a virtual mainstay of the West Ham side this season, playing in 21 of their 28 Premier League games so far.
The famed West Ham academy has produced the likes of Rio Ferdinand, Glen Johnson, Michael Carrick, Frank Lampard and Jermain Defoe, and Tomkins is one of the more current success stories.
Having joined West Ham at the age of nine, Tomkins has now made over 200 appearances for West Ham, and has continued to develop year-on-year.
This season, Tomkins has been part of a formidable centre back partnership with Winston Reid, and his performances have even led to calls that he should be in the reckoning for an England call-up in the near future.
Now though, The Telegraph report that Tomkins has suffered dislocated shoulder ahead of this weekend's visit to face Arsenal.
That means that Sam Allardyce's injury crisis has worsened even more, with the aforementioned Reid already out with a hamstring injury.
James Collins and Cheikhou Kouyate are expected to start at centre back for West Ham this weekend, but Tomkins is now expected to miss the rest of the season in a big blow for player and club.
