The Raiders have confirmed the signing of of tackle Stephon Heyer, guard Justin Smiley and tackle Seth Wand, and added a minor surprise _ the re-signing of center Samson Satele.
Satele was granted unrestricted free agency as a four-year veteran when the new collective bargaining agreement was reached, and thought to be on his way out when the Raiders drafted Stefen Wisniewski in the second round with coach Hue Jackson proclaiming him the starting center.
Last season, Satele started 15 of 16 games in what may have been his best season. He has 59 starts in 63 games over four seasons. With experience at guard, Satele gives the Raiders an option at all three inside positions as well as insurance in case Wisniewski doesn’t develop as quickly as hoped.
Alex Parsons, a practice squad player, has been Oakland’s backup center during recent practice sessions.
The Raiders return to practice at 3:30 p.m. following a morning walkthrough.
