UPDATE: Machado’s surgery went as planned today, but Rich Dubroff of CSNBaltimore.com notes that the Orioles announced that his recovery time is expected to be around six months. The initial timetable had him at 4-6 months, but the new one indicates that he will unavailable at the start of the 2014 season.

11:17 a.m. ET: Manny Machado’s knee surgery is taking place today in Los Angeles, according to Roch Kubatko of MASNSports.com.

Machado has been given a 4-6 month recovery timetable for a torn medial patellofemoral ligament in his left knee, so his status for Opening Day is in some question. Returning in six months would mean mid-April.

He initially hoped to avoid surgery and simply rest and rehab the injury, but doctors advised the Orioles third baseman that going under the knife would lessen his risk of future problems.
