Arsenal defender Chambers out up to 9 months after surgery

Arsenal defender Calum Chambers will be out for the rest of the season after having surgery on a ruptured knee ligament, the club said Thursday.

Arsenal confirmed that Chambers ruptured the anterior cruciate ligament in his left knee during the loss to Chelsea on Sunday.

"Calum has had successful surgery in London on Thursday morning," the club said in a statement.

"The rehabilitation process is expected to take between six to nine months."
"Obviously we have a bad injury with Calum a few days ago that will change our plans at the back."
