Winston Reid has been given the all-clear to play against Chelsea this weekend, West Ham medics have revealed.

The centre-back has recovered from the concussion he suffered in last Sunday’s 1-1 draw at Manchester United in the FA Cup.

Reid was substituted as a “precaution” at Old Trafford but he has trained with the senior squad this week and is in contention to play in Saturday’s Premier League showdown against Chelsea at Stamford Bridge.

Stijn Vandenbroucke, West Ham’s head of medical and sports science, provided an update to the club’s website on Reid’s fitness on Wednesday afternoon.

“Winston Reid came off during Sunday’s FA Cup tie at Manchester United,” Vandenbroucke explained. “He had only trained for two days with the squad and, following discussions between the manager, the medical staff and the player himself, we took the calculated risk of playing him at Old Trafford.

“He played and came off as a precaution following some good communication between the staff and Winston and he has trained this week and will be available to face Chelsea on Saturday.”

Reid has made 21 appearances for the high-flying Hammers this season, 20 of which have been starts.

In other West Ham news, James Tomkins (calf) and James Collins (hamstring) are both closing in on comebacks as they step up the final stages of their rehabilitation.

Vandenbroucke said: “James Tomkins is almost finished and will re-join training later this week, while Ginge (Collins) will return to training during the international break.”
