Kemp physical puts trades in flux

LOS ANGELES -- The San Diego Padres were reviewing medical information before signing off on a trade for Dodgers outfielder Matt Kemp, a source said, with an agreed-upon Thursday deadline to complete the deal fast approaching.

Should San Diego pull out of the trade -- according to USA Today, Kemp's physical revealed arthritis in both hips -- two other trades and three other teams could be affected.

Teams typically have a 72-hour window to perform a physical examination of an acquired player, which the Padres satisfied since Kemp underwent his physical on Tuesday. According to a source, Thursday's deadline can be extended.

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.

In addition, if the Kemp deal crumbles, the Padres might have to rework a three-team trade with the Washington Nationals and Tampa Bay Rays agreed to Wednesday since their interest in catcher Ryan Hanigan -- one of the pieces in that trade -- presumably would be affected by whether Grandal remains a Padre.

The Dodgers are upset that Kemp's medical information leaked publicly, sources told ESPN.com's Ramona Shelburne.

If San Diego general manager A.J. Preller was trying to pry better terms out of the Dodgers, such as more money to cover Kemp's remaining $107 million in contract obligations, the leak of Kemp's medical information could give the Dodgers room for a grievance. The 1996 Health Insurance Portability and Accountability Act protects the privacy of patients' medical information.

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.
