Both players underwent ankle, knee surgery respectively and will miss the opening stages of the season as a result, returning home early from the club’s pre-season training camp in Switzerland.
Unconfirmed reports on Twitter have suggested that the injuries were as a result of both players returning home drunk after curfew and subsequently trying to climb into their hotel room via a balcony, with Carroll allegedly falling and rupturing his ACL.
“We are obviously very sad to hear that Andy and Winston have suffered setbacks. This is a big blow for them and us, but we hope to see them back in action as soon as possible,” manager Manuel Pellegrini told the club’s official website.
“It does mean that we have lost two players in key areas, though, and we’ll continue to work hard with the owners to make further additions to strengthen the playing squad, beyond the five new signings already confirmed.”
West Ham will begin the new campaign away to Liverpool on August 12.
