Jack Collison could end his 14-month injury lay off by playing some part in West Ham's crucial clash against Manchester City this weekend.
The midfielder was an integral part of the Hammers squad last season but suffered a serious knee injury while on international duty in March 2010 and has been out since.
He has made steady progress in his rehabilitation, though, and could play in Sunday's game at Eastlands provided he comes through Wednesday's reserve fixture against Wolves unscathed.
Collison's return would be timely for Avram Grant as the West Ham boss has a number of injury problems in midfield.
Scott Parker has missed the last two games with an Achilles complaint while Gary O'Neil is out for the season with a serious ankle injury.
The club should know the results of tests on Mark Noble's stomach injury on Wednesday. The central midfielder had to come off in the second half of Saturday's 3-0 defeat to Chelsea after feeling discomfort in his stomach after shooting at goal.
