The Raiders signed Akwasi Owusu-Ansah to their practice squad, according to his agent via Twitter.
Owusu-Ansah is versatile enough to play cornerback and safety. However, he also has played some wide receiver.
The Dallas Cowboys, who listed Owusu-Ansah as a wide receiver, selected him in the fourth round of the 2010 NFL draft out of Indiana (Pa.) University.
Akwasi Owusu-Ansah returned 28 kicks for 599 yards for Dallas in 2010-11, averaging 21.4 yards per return. He also returned six punts for 47 yards.
He played in 14 games for the Cowboys and Jacksonville Jaguars, including both his starts for the Jaguars last season, all on defense.
No word from the Raiders on whether they signed any of the six players they worked out Tuesday. They have an open spot on their 53-man roster, which also could be filled by signing someone from their practice squad.
