NEW YORK — Derek Jeter will be sidelined until after the All-Star break because of a new fracture in his broken left ankle — a blow to a New York Yankees team already reeling from injuries and one that raises long-term questions about the 38-year-old shortstop’s future.
Yankees general manager Brian Cashman said Jeter should be able to resume his rehabilitation when the new crack heals, in about 4-8 weeks. Cashman has repeatedly maintained the 13-time All-Star should be able to return at his previous level of play.
Jeter will not require surgery for the break, Cashman said after speaking with Dr. Robert Anderson, who operated on the Yankees’ captain Oct. 20.
‘‘He told me 95 percent of the people that have this, they come back from it fine. You just have to back off,’’ Cashman said.
‘‘But it’s a setback, so it’s not a good situation,’’ he said.
Then again, the Yankees and Jeter repeatedly said all winter that he would be ready to play on Opening Day.
Jeter was hurt last Oct. 13 in the ALCS opener against Detroit. He was limited to five spring training games and 11 at-bats, and when the team left spring training he stayed behind for rehabilitation at New York’s minor league complex in Tampa.
After three straight days of workouts, Jeter went to Charlotte, N.C., and was examined Thursday by Anderson.
‘‘They did a new CT scan which revealed a small crack in the area of the previous injury, so we have to back off and let that heal,’’ Cashman said before New York played Arizona. ‘‘This is obviously a setback. In terms of speculating on when we might see Derek back with us, we’d be looking at some time after the All-Star break.’’
Jeter is among four regulars missing from the Yankees’ lineup, a group that totals 32 All-Star appearances. The defending AL East champions began the day with an 8-5 record.
Outfielder Curtis Granderson broke his right forearm when hit by a pitch from Toronto’s J.A. Happ in his first at-bat of spring training on Feb. 24 and is expected back next month. First baseman Mark Teixeira also hopes to return in May from a partially torn tendon sheath in his right wrist sustained March 5 while with the US team at the World Baseball Classic. And third baseman Alex Rodriguez isn’t expected back until after the All-Star break following left hip surgery on Jan. 16.
