Joba Chamberlain suffered an open dislocation of his right ankle while playing with his son on a trampoline this week. "As we understand, they were at, they have these kids' places where you jump on trampolines and stuff like that," Yankees general manager Brian Cashman said. Chamberlain had surgery on Thursday night at St. Joseph's Hospital and is expected to remain in the hospital for several days for the injury, which resulted in an open flesh wound around the ankle. According to the New York Daily News, Chamberlain lost a significant amount of blood and was taken by ambulance to the hospital.
