James Collins, James Tomkins, Sam Byram and Diafra Sakho should all be back in first team contention soon, reports the club’s official website.
The Hammers are entering a crucial stage of the season, with a series of important games coming up.
The first of those is the FA Cup quarterfinal replay with Manchester United this week, as they try to secure a trip to Wembley.
Following that, they face six crucial games as they look to finish in the top four and win a Champions League place this season.
To do so they will need a full squad, and Head of Medical and Sport Science Stijn Vandenbroucke says four first team players should be available sooner rather than later.
“We welcomed back James Collins, James Tomkins and Sam Byram back to full training,” he told whufc.com.
“Sam is cup-tied but we hope to have all three of them back in first-team contention soon. We have just the one injury at present, and that is Diafra Sakho.”
“Diaf picked up a minor right knee injury in training on Friday and we hope to see him back on the pitch either at the end of the week or the beginning of next week.”
Of those four players, it is arguably Welshman Collins that the Hammers will be keen to welcome back into their side.
He had been impressive alongside Winston Reid this season, with a series of impressive displays alongside the New Zealand international as Slaven Bilic’s side have starred.
He has been missing since the beginning of March though, in which time his side have failed to keep a clean sheet in four Premier League games.
That has threatened to derail their Champions League hopes, and they will be keen to have Collins back to ensure the can compete for as long as possible.
