Yankees general manager Brian Cashman made the announcement before Thursday's game against the Arizona Diamondbacks. Jeter originally dislocated the ankle in Game 1 of the ALCS in October.
"We have to back off and let that heal," Cashman said of the small crack in the bone. "This is obviously a setback. We are looking at, in terms of speculating on when Derek might be back with us, you are looking at some point after the All-Star break."
