The Raiders filled out their eight-player practice squad Sunday, signing four players to join the four added on Saturday.
CB Chimdi Chekwa, DT Vaughn Meatoga, C Colin Miller and RB Jeremy Stewart were signed to the practice squad. The four players signed to the practice squad on Saturday were LB Kaelin Burnett, WR Brandon Carswell, WR Travionte Session and LB Nathan Stupar.
Chekwa (6-0, 194) was waived on Friday in the Raiders' active-roster reduction to 53 players. He played in four games for the Silver and Black after joining the team as a fourth-round (113th overall) draft pick in 2011.
Meatoga (6-1, 295) was in training camp with the Cincinnati Bengals, signing as a non-drafted free agent out of Hawaii. He played in 52 games over four collegiate seasons.
Miller (6-3, 300), who played in four preseason games with the Raiders, was also waived on Friday. The first-year player was in training camp with the Pittsburgh Steelers in 2011.
Stewart (5-11, 215) was in training camp with the New York Jets. He originally signed with the Philadelphia Eagles as a non-drafted free agent out of Stanford.
Teams can establish a practice squad of up to eight players that are free agents who do not have an accrued season of free agency credit or who were on the 46-player active list for less than nine regular-season games during their only accrued season(s). A player cannot participate on the practice squad for more than three seasons.
