While the details are not yet known, Jonathan Tannenwald is reporting that the Philadelphia Union acquired Jeff Parke in a trade with the Seattle Sounders.

The Union have acquired Abington, Pa., native and Drexel University product Jeff Parke via a trade with the Seattle Sounders, multiple sources confirmed Friday morning.

Parke was Seattle's best defender in a year that they had the second best defense in the league. But, the team is well over the salary cap/budget for 2013 and needed to make changes. Seattle's number one need in the deal would be for Allocation Money. As soon as details of the deal are known we will of course update the story with what was acquired and how that changes things for Seattle.

With today's Re-Entry Draft Stage One (Noon Pacific) this may not be the only move of the day for the Sounders, and certainly won't be within the league.
