Pistons trade Johnson for Bucks' Oberto

In an effort to clear more salary cap space, the Detroit Pistons have sent forward Amir Johnson(notes) to the Milwaukee Bucks for newly acquired Fabricio Oberto(notes), a league executive told Yahoo! Sports.

The Pistons plan to buy out Oberto's deal and make him a free agent. The San Antonio Spurs sent Oberto to the Bucks as part of a four-player trade for Richard Jefferson(notes) earlier on Tuesday.

Oberto is expected to re-sign with the Spurs.
