The midfielder fell badly in training and Manchester United confirmed he is set to spend a significant chunk of time on the sidelines after suffering ligament damage
The England international fell badly in training on Tuesday, with the club confirming the extent of the injury on Thursday.
Michael Carrick has had surgery this morning on his left ankle ligaments and will be out for 10-12 weeks. #mufc— Manchester United (@ManUtd) July 17, 2014
New manager Louis van Gaal admitted on Thursday that the losing the former Tottenham man would have a big impact on the team.
"There is, for example, Michael Carrick. He is injured, that is in my opinion a big blow because he is an experienced player," he told the press.
The injury hinders Carrick's chance of impressing his new manager, with the Dutchman already sanctioning the big-money arrival of midfielder Ander Herrera, and a long-standing interest in Arturo Vidal ongoing.
United has been dealt a blow in its chase for the Chile star, though, with Juventus chief executive Giuseppe Marotta insisting Vidal is "not for sale" on Wednesday.
Carrick has made over 350 United appearances since moving from White Hart Lane in June 2006, and played 29 Premier League games last term, an Achilles tendon injury limiting his mid-season availability.
