Arsenal have cancelled their pre-season tour to the United States after a small number of positive COVID-19 cases at the club, the club announced on Tuesday.

Arsenal were set to travel to the U.S. this week to participate in the Florida Cup alongside fellow Premier League team Everton, Serie A champions Internazionale and Colombian club Millonarios.

"Following a small number of positive COVID tests among the planned party to travel to America tomorrow, we have sadly been forced to withdraw from the Florida Cup," Arsenal said on their Twitter account. "This difficult decision is based on ensuring the health and wellbeing of our players and staff."

Florida Cup organisers issued the following statement: "We are disappointed that Arsenal have decided not to participate in the 2021 Florida Cup. We wish the members of the Arsenal traveling party who tested positive for COVID-19 a speedy recovery as we continue making final preparations for the event. We will be in communication with fans who purchased tickets to see Arsenal in Orlando regarding their options."

The London side were scheduled to take on Inter on Sunday and then potentially face on July 28 the winner of Everton's game against Millonarios.

Everton midfielder Fabian Delph will not travel with their squad to Orlando "as a precautionary measure after coming into contact with someone who has since tested positive for COVID-19," the Merseyside club said in a statement.

Everton said Delph would resume his pre-season training as soon as his period of self-isolation ended.

Mikel Arteta's Arsenal team started their pre-season preparations in Scotland and played two games, losing 2-1 to Hibernian and drawing 2-2 with Rangers.

Arsenal finished eighth in the Premier League last term.

They begin their 2021-22 campaign at promoted Brentford on Aug. 13.
