Leicester boss Claude Puel confirmed that Daniel Amartey was taken to hospital after suffering a suspected broken leg during the draw with West Ham on Saturday night.
Amartey had to be carried from the pitch on a stretcher during the closing stages of the Premier League game at the King Power Stadium.
After receiving oxygen from medics, the 23-year-old midfielder, who played as a right-back against the Hammers, left the field with his left leg in a brace after appearing to get his studs caught in the turf.
Puel said the club are awaiting news about the extent of the injury, he said in his post-match press conference: “My first thoughts are for Daniel, I hope it is not a serious injury, of course.
“He will have an exam and we will see after. He has gone to the hospital, of course.
“He had a strong game and battled for the team. He won his battles and then sacrificed himself to save an opportunity.”
Photographs online appear to suggest Amartey has suffered a break and fears are he will probably not play again this season. However, Puel would not be drawn on that, saying: “I can’t have an opinion. We will wait for news.”
The low of Amartey’s injury came shortly after the high of Wilfred Ndidi scoring a last-minute equaliser for Leicester, who had been behind since Fabian Balbuena’s strike after half an hour.
Ndidi’s goal rescued Leicester from a third straight Premier League loss, a defeat which would have been scrutinised further following Puel’s decision to drop Jamie Vardy.
The striker touched the ball just 11 times during the defeat to Arsenal on Monday and left the field of play five minutes before the final whistle at the Emirates Stadium because of a stomach problem. The issue also caused him to miss a training session this week.
Vardy resumed training on Thursday and declared himself “back to full strength” on Instagram a day later. However, Puel decided to leave out his star striker and revert to a 4-2-3-1 formation with Kelechi Iheanacho leading the line in attack.
Asked about Vardy’s omission, Puel said: “I make the decisions about my players and always try to make the best possibilities.”
Puel’s side played against 10 men for much of the match after West Ham captain Mark Noble was sent off in the 38th minute for a late, high sliding challenge on Ndidi.
West Ham manager Manuel Pellegrini said: “I haven’t seen the action yet so I can’t give my opinion but I will say what I always say when those things happen, it is the decision of the referee.
“Mark told me he had no bad intentions and he tried to get the ball, but maybe he arrived late.”
Ndidi’s equaliser was cruel on West Ham, with Pellegrini full of praise for the way his team defended.
“I think we were very unlucky. We defended so well for the whole game but particularly for the 55 minutes with one player less. At times, it was a masterclass in defending from us,” he said.
“When it was 11 against 11 most of the game was in their half and we dominated. We must continue working and we are unlucky with the goals we are conceding. Leicester is always a difficult stadium to win in.”
