Terrible news comes via an early morning report by Mark Feinsand:

According to sources, Harlan Chamberlain collapsed at his home in Lincoln, Neb. He was listed in critical condition at St. Elizabeth Regional Medical Center in Lincoln, a nursing supervisor there told the Daily News on Sunday night. Chamberlain learned the news after the Yankees' loss to the Red Sox at Fenway Park. ...

Sources said Chamberlain broke down in tears inside the clubhouse, as manager Joe Girardi consoled him.

Our thoughts are with Mr. Chamberlain and those close to him.
