Hugo Lloris suffered a potentially serious arm injury and was hospitalised as Tottenham lost 3-0 at Brighton on Saturday.
The France international, who won the World Cup with his country in 2018, required on field treatment as oxygen was administered before he was taken away on a stretcher. Lloris was then transferred to a nearby hospital.
Tottenham coach Mauricio Pochettino said after the match: “He is in the hospital now. The club is going to communicate the problem but we need to wait. The club will communicate because I think it is a big problem in his arm.
“It was a massive impact after three minutes. It had a massive impact on the game. To concede and lose your captain is a massive impact emotionally and for the team.
“After 30 minutes it was 2-0 and we tried to find a solution but it was impossible. It’s a very difficult moment but we need to keep going.”
Lloris’ injury capped a miserable afternoon for Tottenham following their embarrassing 7-2 defeat against Bayern Munich in the Champions League on Tuesday. Maupay’s goal and two from Aaron Connolly meant Tottenham are still without an away league win in nine months.
Pochettino said ahead of the match he wanted to stay for five more years at Spurs but another defeat has cranked up the pressure on him.
“I feel very sorry for the fans. We are living in a tough moment. When we were on the top we were together and now this movement has arrived we need to stick together,” he added.
“This feeling is not so good. It is new for everyone in the club.
“Now is a moment to be strong.”
