Tests showed there are no microfractures in Chamberlain's ankle, which he hurt on Thursday while playing with his son.
Earlier on Saturday, general manager Brian Cashman told reporters that he visited Chamberlain in the hospital on Friday. Chamberlain told the GM that doctors said the right-hander could be back on a mound pitching in July.
If infections don't occur -- and at this point they haven't, there is actually a chance Chamberlain could pitch in a game against this season, although the optimistic outlook of July would be a return to pitching -- not a return to pitching in a game.
"That's the optimistic side," Cashman told reporters (via MLB.com). "As any orthopedic will tell you, you have to go through the whole spectrum [of rehab].
"The way I work this stuff, my mindset is, until they're close to knocking on the door, I [don't worry about it]. Obviously, in Joba's case, it's still a question of when he comes back. I just hope we're in a position where he can come back."For more baseball news, rumors and analysis, follow @EyeOnBaseball on Twitter, subscribe to the RSS feed and "like" us on Facebook.
