The deal was jeopardized after Kemp's physical revealed arthritis in both hips. The Dodgers were upset that Kemp's medical information leaked publicly, sources told Shelburne.
The Padres and Dodgers agreed to a trade one week ago that would send Kemp, catcher Tim Federowicz and $32 million to San Diego for catcher Yasmani Grandal and pitching prospects Joe Wieland and Zach Eflin. The Dodgers then planned to trade Eflin and their pitching prospect Tom Windle to the Philadelphia Phillies for shortstop Jimmy Rollins.
Kemp was the runner-up for the National League MVP in 2011, but he has dealt with a long string of injuries since April 2012. He underwent two shoulder surgeries and a major operation on his right ankle and dealt with three hamstring strains. Until now, he had never been diagnosed with a hip ailment.
The 30-year-old hit 17 of his 25 home runs and drove in 54 runs after the All-Star break last season. The Dodgers have been looking to trade an expensive veteran outfielder -- either Kemp, Andre Ethier or Carl Crawford -- for more than a year.
