Manchester City have confirmed two more players and another member of staff have tested positive for COVID-19.
Goalkeeper Scott Carson and 18-year-old midfielder Cole Palmer are the latest players affected by the recent outbreak at the club and will now isolate.
City were without six other players for their Premier League victory at Chelsea last Sunday following positive tests.
"Manchester City FC can confirm that Scott Carson, Cole Palmer and one member of staff have tested positive for COVID-19," a club statement read.
"Both personnel will now observe a period of self-isolation in accordance with Premier League and UK Government protocol on quarantine.
"Everyone at the club wishes Scott, Cole and all of our other colleagues a speedy recovery ahead of their return to work, training and competition."
With first-choice goalkeeper Ederson being one of the other players already isolating, news of Carson's positive tests leaves City short of options in that position for Wednesday's League Cup semi-final against Manchester United.
Zack Steffen is set to play again after featuring at Chelsea with 18-year-old James Trafford, who has been involved in a Champions League squad this season, possibly coming onto the bench.
Ferran Torres, Tommy Doyle and Eric Garcia are the other players also currently isolating while Kyle Walker and Gabriel Jesus, who tested positive on Christmas Day, have now completed their quarantine.
