ALAMEDA -- The Raiders opened practice Wednesday without left tackle Menelik Watson, an indication they will open with the same offensive line protecting Terrelle Pryor as they used in a season-opening win over the Indianapolis Colts.
Tight end David Ausberry (shoulder) is continuing to work with athletic trainers in during the media window, which means he could be closer to returning than Watson.
With a practice squad opening after promoting Matt McCants to the 53-man roster, the Raiders signed another offensive tackle in Jack Cornell, who played on the Baltimore Ravens practice squad last season.
It is likely the starting tackles against the Jacksonville Jaguars Sunday in the regular-season opener at O.co Coliseum will be Khalif Barnes on the left side and Tony Pashos on the right.
When Watson does return, assuming his injury is not long-term, it will be interesting to see whether Barnes moves back to right tackle or instead surfaces as at one of the guard spots in place of left guard Lucas Nix or right guard Mike Brisiel.
Nix in particular struggled against Indianapolis, and Pashos played very well at right tackle despite having just one week to perform.
Jacksonville coach Gus Bradley, the defensive coordinator for the Seattle Seahawks last season, talked about the dilemma of defending Raiders quarterback Pryor.
Indianapolis discovered that coming with a hard rush could backfire after Pryor would escape, with defenders having no chance to catch up once he got past the line of scrimmage.
``There are different philosophies with a running style of quarterback,'' Bradley told Bay Area media by conference call. ``Some teams ill blitz, some will challenge their rush to take care of him, others will spy. We have to come up with a plan that best fits our personality and then execute it.
``He's a threat, though. With him back there, there's a new dimension to their style of offense, which if not contained, you have an opportunity to give up big plays.''
