The Hammers midfielders are nearing a return to the first team after overcoming long-term injuries, though manager Sam Allardyce expects to use them only sparingly
Collison has been sidelined for six months with a knee problem, while Diarra’s summer move to east London has been blighted by injuries, limiting him to just a single start against Crewe in the Capital One Cup.
But the pair are close to a return to action, welcome news for the Hammers who will be without Mohamed Diame for the next 12 weeks, who was injured in West Ham’s 3-2 loss to Liverpool.
Diame’s absence forced Allardyce to field centre-back James Tomkins in midfield, but the 58-year-old is reluctant to rush Collison and Diarra back despite the injury crisis.
"Alou Diarra [is close], but he hasn't played a Premier League game yet, so he hasn't felt what it is like to play there and that would be difficult for him after a three-month lay-off,” Allardyce told talkSPORT.
"Jack Collison might be close in the next couple of weeks to actually start joining in but he hasn't kicked a ball since the play-off final last year.
"At least to have the bodies back and bring them on from the subs bench is going to be important to us."
