Derek Jeter underwent further tests on his fractured left ankle today at Columbia Presbyterian Hospital to determine if he requires surgery. "It's possible,'' Joe Girardi said of surgery."That's why they are having more tests.'' Early this morning the indication was that Jeter wouldn't need surgery but that changed. "When I went back there the doctor said, 'I am not saying you are going to need (surgery) but the next tests will determine if you need it,'' Girardi said. A CT Scan and MRI confirmed an ankle fracture Sunday afternoon. Jeter will see Dr. Robert Anderson, a foot and ankle specialist in Charlotte in the coming days. He's currently in a splint and on crutches. He isn't at Yankee Stadium for Game 2 and is not going to Detroit. With or without surgery, Jeter is expected to need three months to recover. If that goes well he would be ready for the start of spring training.
