Toronto FC captain Michael Bradley faces a lengthy stint on the sidelines for up to four months after club GM Ali Curtis said he needs surgery for a "severe and complicated" injury.

The U.S. international suffered an ankle injury in the 2019 MLS Cup in November, in which Toronto lost to the Seattle Sounders.

Curtis said the 32-year-old Bradley will have surgery on Tuesday in New York, a procedure to be performed by Dr. Martin O'Malley of the Hospital for Special Surgery, adding that the surgery was "the last resort."

"We are going to be careful and cautious about this," Curtis said. "But we're confident that once he has the surgery that he'll be able to return to play. It'll take probably approximately four months. Now that could be shorter or it could be lengthier depending on how we manage that process."

The news came as a surprise to Bradley's club and country teammate Jozy Altidore, who said on Monday that the injury "was handled poorly."
