The operation will likely force Machado out of action for a four to six month time frame, which would put him near an Opening Day return.
Per Roch Kubatko:
I’ll beat the rush and pass along that it’s going to be a “successful” surgery and the time frame of a four- to six-month recovery period will remain unchanged.
Five months would put Machado in the middle of March, still enough time to get ready for opening day at Camden Yards. In the meantime, he can work on his upper-body strength.
As you’ll recall, Machado suffered the devastating knee injury during just days before season end while running out a ground ball in Tampa Bay.
Originally, it was not expected that Machado would need to have surgery though doctors informed him that if he continued to play on it without repairing his knee, he could potentially face worse damage down the road.
