The Raiders concluded their annual training camp at Napa today after what many consider a wildly successful three weeks and riding high from a preseason victory over the Saint Louis Rams. The Raiders face off against the Minnesota Vikings in the second preseason matchup of the season on Saturday night in Minneapolis. When the Raiders return from Minneapolis, they will begin their regular weekly schedule of practice and preparation and head toward the regular season finale.

The Raiders have managed to break camp without any devastating injuries to this point, though wideout Rod Streater’s illness did hold him back somewhat and now wideout Andre Holmes has suffered a broken hand which will sideline him for a few weeks. The first game of preseason highlighted a few areas where the depth chart might need reshuffling and where position battles are still tight. The Raiders also made a roster move – cutting one wideout and signing another – which changes the dynamics of some other position battles.

There will be a few key players to watch on Saturday night for Raider fans to see how these position battles are shaping up, how players are fitting into the new systems, or how young players might be developing as the season approaches. Here are five players to keep an eye on:
