Joba Chamberlain (ankle) expects to be out of a walking boot in about two weeks.

Chamberlain dislocated his right ankle while jumping on a trampoline last month, but he has already resumed workout at the Yankees' complex in Tampa, including playing catch in the outfield Friday with his right knee on a stool. While he hopes to return before the end of the season, he can't afford any significant setbacks with his ankle or surgically-repaired right elbow.

Joba Chamberlain (ankle) was released from the hospital.

According to Yankees GM Brian Cashman, Chamberlain will be in a non-weight bearing hard cast for six weeks, and a walking boot after that for an indefinite amount of time. "So far everything's coming back extremely positive," Cashman said. "Obviously he's been dealing with a lot. His healing process is really significant. So we're counting on that in this case, too."

Yankees GM Brian Cashman downplayed the idea the that Joba Chamberlain (ankle) could make a return to the team in July.

Chamberlain suffered an open dislocation of his right ankle Thursday while jumping on a trampoline. ''That's the optimistic side,'' Cashman said.''I'm only getting that from Joba. I don't think anyone can tell anything directly right now." Chamberlain's return from an injury that could be career-ending this season is highly unlikely.

The Newark Star-Ledger reports that Joba Chamberlain is likely to miss the entire 2012 season following surgery to repair an open dislocation of his right ankle.

Chamberlain, who is also coming back from Tommy John surgery, suffered the gruesome injury while playing on a trampoline with his son. Yankees general manager Brian Cashman wasn't willing to put a timetable on the righty's return, but referred to it as a "significant injury" and that he "would like to believe it's not" a career-threatening ailment. Even if it doesn't end his playing career, it's possible his Yankees career is over. Chamberlain is arbitration-eligible for the final time this winter.

Joba Chamberlain underwent surgery Thursday to repair a dislocated right ankle.

He apparently suffered the injury while playing with his son. It's a shame, as Chamberlain's recovery from Tommy John surgery seemed to be progressing ahead of schedule. The Yankees have not provided a timetable for the right-hander's return, but general manager Brian Cashman called it a "significant" injury. Chamberlain had hoped to come back from elbow surgery sometime before the All-Star break, but that might not happen now.

Joba Chamberlain (elbow) on Thursday threw one curveball and five sliders from flat ground.

Chamberlain was supposed to begin working in his breaking stuff Friday, but he beat the timetable by a day. "Dr. Andrews, Larry (Rothschild) and (trainer) Stevie (Donohue) suggested I throw the slider because I had been throwing the fastball and you throw your slider off your fastball,'' said Chamberlain. The righty will do the same thing Monday before throwing breaking balls off the mound on March 16.

Joba Chamberlain (elbow) is scheduled to begin throwing sliders and curveballs during a bullpen session on March 11.

"I am going to throw Tuesday and Friday this coming week and the week after that I can start spinning stuff,'' said Chamberlain. "I will start the slider first and then throw the curveball." The right-hander is progressing well from Tommy John surgery, starting with throwing off flat ground before progressing to a half-mound and then a regular mound. The Yankees are hopeful he'll be able to return to the bullpen sometime in June.

"It was a huge loss when we lost him last year and it will be a huge get when we get him back," Cashman said. Chamberlain is reportedly ahead of schedule in his recovery and has said he's hoping to return early in the year. Realistically, though, he's going to miss the first couple months of the season. When ready, he'll add another big arm to a formidable Yankees bullpen.
