Washington released Bowen back in February in a move that freed up $5.5 million in cap space for the Redskins.
Bowen, 30, originally signed on with the Cowboys as an undrafted free agent out of Hofstra back in 2006. He spent the first six years of his career in Dallas before joining the Redskins in July of 2011.
Last year, Bowen was limited to playing in just eight games for the Redskins after he began the year on the PUP list, due to a knee injury. He finished the season with 11 total tackles and a pass defense.
