Cornerback Taiwan Jones and linebacker Sio Moore suffered undisclosed injuries, and they weren't able to finish practice.
They were among 16 players that missed some or all of practice. Allen said he is hopeful of getting back some players soon. . . . Andre Gurode worked at right guard and Tony Bergstrom at left guard with the first-team offense. Gurode and Bergstrom got all the reps because Mike Brisiel and Lucas Nix didn't practice and weren't able to compete for job openings.
Allen said it's crucial for the Raiders to find five reliable offensive linemen as soon as possible, but it's more important to make the proper decisions before the regular-season opener.
