Leicester City manager Brendan Rodgers has confirmed three of his players are being kept away from the rest of the squad after displaying coronavirus symptoms.
Leicester are scheduled to face Watford at Vicarage Road in the Premier League in a lunchtime kick-off on Saturday.
Rodgers did not confirm which players may be affected.
"We've had a few players that have shown symptoms and signs (of coronavirus). We've followed procedures and (as a precaution) they have been kept away from the squad," Rodgers said.
"We've self-isolated the three of them and we'll see how that develops in the next couple of days

"This is about health, this is more than football. This is about players and their families, so any risks that are there for their health and everyone else's, we have to mitigate against that.
"The game is all about the players and the fans. If you have one of those not there, it's obviously not the same."
It remains unclear whether the Premier League will be suspended, or whether games will be forced to be played behind closed doors as the coronavirus pandemic spreads, but Rodgers says the public's safety must be paramount.
"Of course from a football perspective it would be a shame, but I think the public's health is the most important aspect in all of this," Rodgers said.
"For us working in football it is having that agility to move with whatever happens.
"Of course we are clearly guided by the government and federations so we have to get on with our work and prepare as normal of course but this is something that can change very, very quickly."

Pereira out for season with torn ACL
Rodgers also confirmed Portugal international Ricardo Pereira will miss the rest of the season after suffering a torn anterior cruciate ligament (ACL) in Leicester's 4-0 win over Aston Villa on Monday.
"Ricardo Pereira will unfortunately be out now for the rest of the season, which is a huge blow for us," Rodgers admitted. "He is a fantastic player.
"He had a challenge in the game which led to his ACL being injured so he will be for the remainder of the season.
"James Maddison will be out for a few weeks, probably until after the international break."
