I just learned moments ago on the opening of the Red Sox game on NESN that Jerry Remy has had cancer surgery, and will be missing from the NESN booth for the near future, as he takes a leave of absence to recover. Dennis Eckersley will handle the color commentary on NESN during this homestand, and Dave Roberts will work with Don Orsillo during the next roadtrip.
Don Orsillo read statements from Jerry, the Red Sox and NESN before the game. No one was specific as to the nature of the cancer (I did read later on it was lung cancer), but he was forced to quit smoking earlier this year. (Jerry had the procedure done over the winter, but is just now revealing that he's had the surgery and is currently suffering a setback from it.)
Here is more from NESN.
All our thoughts and prayers are with Jerry and his family for his speedy recovery.
