With their offensive line wracked by injuries and ensuing questions, the Raiders on Saturday signed offensive lineman Jack Cornell to the active roster off the practice squad and waived guard Antoine McClain in the corresponding roster move.
Center Stefen Wisniewski (right knee) is doubtful to play for Oakland Sunday night against San Diego while right tackle Tony Pashos (groin) is questionable, as is rookie tackle Menelik Watson, who just finished his first week of practice after undergoing knee surgery prior to the season opener. Watson was seeing reps at right tackle in practice Friday after moving to left tackle in the wake of Jared Veldheer’s triceps surgery late in training camp.
The 6-feet-6, 320-pound Cornell, who spent the 2012 season on Baltimore’s practice squad as an undrafted rookie free agent, is more of a tackle than a guard.
If Wisniewski cannot play against the Chargers, Andre Gurode will start at center and either Lamar Mady or former starter Lucas Nix, who is questionable with an ankle injury, will go at left guard for Oakland.
