Sandy Alderson is battling cancer, will undergo chemotherapy next week

The Mets have announced that general manager Sandy Alderson has cancer. The cancer is treatable and he will undergo 8 to 12 weeks of chemotherapy. Consequently, Alderson will miss next week's Winter Meetings in Nashville, Tennessee.

Alderson was not able to attend the general managers' meetings in November due to a medical procedure. It's unclear if the medical procedure is related to his cancer. Assistant general manger John Ricco filled in for Alderson during the GM meetings and the same can likely be expected for the Winter Meetings.

Also, Alderson collapsed during a press conference at Citi Field in early November. It was reported that he fainted because he didn't have breakfast and felt "lightheaded." It has not been the best offseason so far for the 68-year-old.

Alderson is coming off the Mets' first winning season under his leadership and one that saw them reach the World Series. Next year will be Alderson's sixth year as general manager of the Mets.
