Yankees reliever Joba Chamberlain left the team after Sunday's game to tend to his ailing father, the New York Daily News reported.
The newspaper said that Harlan Chamberlain collapsed at his home in Lincoln, Neb., and was listed in critical condition at St. Elizabeth Regional Medical Center in Lincoln, citing a nursing supervisor at the facility.
Chamberlain learned of his father's condition after the Yankees' 8-5 loss to the Red Sox at Fenway Park. Chamberlain returned a telephone call from his sister after the game and broke down in tears in the clubhouse as manager Joe Girardi consoled him, according to the report.
Asked about the situation, Girardi told the Daily News, "Personal stuff stays in there," pointing to the clubhouse.
