Update: Beltran underwent ‘minor’ knee surgery without Mets permission, out 8-12 weeks

Update – 10:44 p.m.: Info from Kevin Burkhardt: “Mets knew about this, but didn't agree with surgery.”

Update – 10:16 p.m.: Joel Sherman: “Mets are definitely claiming Beltran procedure done without their blessing, and are threatening some form of action.”

Not good.

Update – 10:01 p.m.: Two things: Twelve weeks from now is April 7, the second game of the season.  But that’s when his spring training will begin.  So don’t expect Beltran until the second month of the season.

Kevin Burkhardt, on SNY, also reports that the surgery may have been done without the Mets blessing.

Update – 9:54 p.m.: Steve Popper says out 12 weeks and performed by doctor that invented microfracture surgery.  Joel Sherman said Beltran’s knee worsened during the offseason and had surgery in Colorado today due to osteoarthritis.

Update – 9:49 p.m.: Another Sherman update.  Says it wasn’t microfracture, as Heyman reported.

Update – 9:46 p.m.: Sherman’s source says “scope clean up.”  Then Sherman writes “but Mets are acting like this was more than routine.”

Original post: According to Sports Illustrated, Carlos Beltran underwent “minor” knee surgery earlier today.

He will miss 8-12 weeks, according to the report.

Joel Sherman heard that Beltran may have gone through with the surgery without the Mets permission.
