Marc Lancaster first reported it, and here’s the Reds.com story:

Ken Griffey Jr.’s comeback season has come to a close.

It will end in the spot Griffey has found himself all too often during his time with the Reds — on the operating table.

On Monday, Junior will have arthroscopic surgeries to clean out both his left knee and the scar tissue surrounding the incision at the point of his 2004 right hamstring surgery. The procedures will be performed by Reds medical director Dr. Timothy Kremchek.

The 35-year-old Griffey is expected to recover from both surgeries in time for Spring Training in ’06.

We all knew this was coming, but it’s still disappointing. At this point, with eleven games left, there was no real compelling reason to get him back on the field.
