Dean (shoulder) was a limited participant at the Raiders' practice Wednesday, Ryan McFadden of ESPN.com reports.
Dean recorded 10 total tackles (seven solo), including 0.5 sacks, in the team's 26-14 win over the Chargers on Sunday, but he may have suffered a shoulder injury during the contest. The linebacker will have two more chances to log a full practice and prove his health before the Raiders face New Orleans in Week 3.
