"What, you guys didn't know that"

-Cito Gaston, on Dustin McGowan's knee surgery

Yeah, that's right—McGowan had knee surgery on July 9th. Today, Jordan Bastian reported that when asked about recovery time-lines for injured starters Shaun Marcum and Dustin McGowan, Cito dropped that bomb. Apparently, it was common knowledge to Cito.

The story goes that McGowan had surgery to repair cartilage when he injured his knee while doing conditioning drills; Riccardi indicated that the injury will take around six weeks to recover from the operation. McGowan was doing light work in the farm after recovering from right shoulder surgery last July.
This pretty much puts the lid on any hope of McGowan coming back this season.

Hopefully the knee injury is as nonchalant as Gaston's response.
