West Ham United manager David Moyes has admitted that he is worried about Winston Reid after the defender was stretchered off in the 4-1 defeat to Swansea City on Saturday.

The Hammers were heavily beaten in an abject display in South Wales, with the New Zealander adding injury to insult and having to be removed from the action in the first half.

Reid was knocked unconscious in a goalmouth scramble, but Moyes has stated that he is worried about the potential for a knee injury that the West Ham defender sustained.

“Winston has obviously been knocked out and concussed,” the Hammers boss told the club’s official website.

“It’s his secondary injury we’re more worried about. When he’s fallen he’s hurt his knee or damaged his knee in someway so I think that’s our biggest concern. More his secondary injury.

“He’s awake and in the dressing room, he’s fine now, he’s talking. He’s got no problem that way, I think they have got to get it done [scan] and checked to see what the knee problem is.”

Reid is a defensive leader for West Ham, with his physicality and experience key attributes for the London Stadium club.

However, the no-nonsense centre-half has had his season disrupted by injuries and has only recently returned to availability for Moyes and the Hammers.

West Ham supporters will hope that Reid’s ailments are not as serious as first thought, with the club needing the defender to play a role in avoiding any potential relegation stress as the campaign comes to a conclusion.
