N’Golo Kante and Ruben Loftus-Cheek will not travel with Chelsea for their preseason tour of the United States due to their Covid vaccination status.
Entry rules for the U.S. say that all visitors over 18, barring American citizens and other limited exceptions, must be double vaccinated against the virus.
The club confirmed the news when announcing a 29-man squad of players that will face Club America in Las Vegas, Charlotte FC in Los Angeles and Premier League rivals Arsenal in Florida.
Loftus-Cheek tested positive for COVID-19 in August last year while France international Kante returned a positive test ahead of a Champions League group game against Juventus the following month.
Manager Thomas Tuchel said at the time that did not know how many of his players had been vaccinated and although he had taken the jab, he would not force others to do so.
Chelsea travelled on Saturday and will spend a week in a training camp in LA before their first game.
