Tight end Mickey Shuler, defensive back Akwasi Owusu-Ansah and four other players who finished the season on the Raiders' practice squad signed reserve/future contracts, the team announced Wednesday.
Offensive guard Jason Foster, offensive tackle Jason Slowey, linebacker Jerrell Harris and wide receiver Travionte Session also signed.
Shuler, who was drafted by Minnesota in the seventh round in 2010 out of Penn State, played six games for the Miami Dolphins as a rookie. Dallas drafted Owusu-Ansah in the fourth round out of Division II Indiana University of Pennsylvania in 2010. He played 10 total games for the Cowboys in the 2010 and 2011 seasons, returning 28 kicks for 599 yards.
The 49ers drafted Slowey in the sixth round in 2012 out of Western Oregon but cut him during training camp.
The Raiders initially signed Session last year as an undrafted rookie from Nevada, and he spent time in training camp. Foster initially signed with the Colts in 2012 as an undrafted rookie from Rhode Island.
Atlanta signed Harris in 2012 as an undrafted rookie from Alabama. He spent time on practice squads with Jacksonville and New England before being signed to Oakland's practice squad on Nov. 28.
