Leicester City have said a COVID-19 breach among their players is "extremely disappointing," after reports that three of the squad attended a party.
"The club has made its expectations around adherence to COVID-19 protocols abundantly clear to all its personnel," a Leicester spokesperson told the Telegraph.
"It is extremely disappointing, therefore, to learn of a breach that had the potential to undermine the efforts of club staff to protect the environments in which our teams train and play. Appropriate measures have been taken to prevent our team bubbles being compromised.
"We wholly expect our people to behave in a way that reflects the national effort and the sacrifices made by our communities to control the spread of the virus. Those involved have apologised for their poor judgement. Our response to the matter will be concluded internally."
"It was a decision I made, an internal situation last weekend. It is not the standard we expect," Brendan Rodgers said after the game.
"They [the players who breached COVID-19 guidelines] are all good guys, good lads, but we have a standard on and off the pitch that we have to adhere to. The boys will rejoin the group after this game.
"It's something we have dealt with. It's disappointing behaviour, it's a mistake. It's not what we are about."
When asked if there was a temptation to let the players still compete due to the game's importance -- Leicester are one of several teams battling for a Champions League spot -- Rodgers said it didn't cross his mind.
"You can do if you're soft. To be a winner you have to act like a winner," he added.
