Chamberlain is expected to tell media that when he was hurt last week, there was no major blood loss resulting from the injury, as has been reported, according to sources.
He's also expected to say that at no time was his life in jeopardy and unless something unforeseen happens in his rehabilitation, his career will not be in jeopardy either, sources told Olney.
Chamberlain suffered a dislocated ankle last week while bouncing on a trampoline at a recreation area, where he was playing with his son. He needed surgery and will be in a cast for six weeks, general manager Brian Cashman said. There is no timetable for when the 26-year-old will resume pitching.
The 6-foot-2, 240-pound right-hander was working his way back from elbow ligament replacement surgery and was expected to return in June.
