The media learned yesterday that Naoyuki Shimizu recently had surgery on his left knee and will require about 3 months until he's ready to start running again. An unnamed team rep told reporters that he might, just barely, make it back in time for the start of the 2012 season.
Shimizu is in the final year of a 2-year deal and is looking to stay in Yokohama.
UPDATE @ 7:50pm - My apologies, I meant to say knee, not elbow... And it was apparently surgery to get the knee cleaned out.
UPDATE @ 8:26pm - Shimizu was released from the hospital on the 12th and will require 5-6 months for a full recovery.
