Major League Baseball pitcher Joba Chamberlain has been reportedly involved in a trampoline accident which injured his right foot – and reports say that the accident might threaten his comeback.

According to reports, Joba Chamberlain was injured on Thursday while jumping on a trampoline with his five-year-old son at a play center in Tampa, Florida. The New York Yankees pitcher came down on his right foot, which caused severe damage to his ankle. The greatest fear was that the bone, which was protruding through the skin, would become infected. His attending doctors will continue to monitor the wound from this trampoline accident.

Joba Chamberlain was released from St. Joseph’s Hospital on Sunday and will spend the next six weeks in a cast as he recovers from surgery to repair his dislocated right ankle.

Chamberlain’s discharge from the hospital is a sign that doctors are confident that the worst danger of an infection in the bone from the trampoline accident has passed, and that the baseball player could return to pitching this season.

“It’s good to see him out, and he’s doing well,” New York Yankees Manager Joe Girardi said. “I am optimistic he’s going to pitch for us this year. I am.”

Yankees General Manager Brian Cashman also released a statement about Joba Chamberlain’s condition: “So far, everything looks great. The risky stuff is all we care about now for him personally to get out of the woods. After that we can worry about baseball stuff.”

Joba Chamberlain also missed most of the last season due to his elbow injury.
