Carson Palmer For fans celebrating the Oakland Raiders' preseason win over the Detroit Lions this past Saturday, it was fairly clear that the team's depth chart is nearly etched in stone.

However, whether media induced, earned by performance or a result of injuries, there are a few positions to keep an eye on as changes may come.

Quarterback: Starting QB Carson Palmer had another shaky performance against the Lions, throwing two interceptions and no touchdowns. 

Palmer is operating under a brand new (for him) timing West Coast offense which may explain some of his miscues. The coaches have reiterated that Palmer is in no danger of losing the first-string position. Still, No. 3 QB Terrelle Pryor delivered another electrifying performance, posting a solid three of five pass attempts for 137 yards and two touchdown passes. 

He also added a 59-yard scramble on a broken third down play. He then capped off the drive with another 17-yard rushing touchdown.

Even No. 2 QB Matt Leinart, who did not play Saturday thanks to a finger injury suffered against the Arizona Cardinals last week, has looked far more comfortable and poised in the pocket than Palmer. No doubt, it's a completely different game during the regular season, but the QB position will definitely bear watching.

Wide Receivers: Part of Palmer's problems may stem from his starting receivers Denarius Moore and Jacoby Ford, who at times have looked as though they're trying to reel in his passes with hands made of cement.

Moore and Ford are both listed as questionable right now, Moore with a hamstring injury and Ford with a foot issue. Oakland's other starter, Darrius Heyward-Bey has also been bothered by a shoulder injury that saw him leave last week's game, although it didn't appear to affect him against the Lions. 

Third-stringers Juron Criner, who had two touchdowns against Detroit, and Rod Streater, who had five grabs for 56 yards, are certainly poised to move up a slot or two on the depth chart. This becomes a necessity if Ford and Moore can't suit up for the season opener.

Kicker: Kicker Sebastian Janikowski, who was one of the Raiders' few bright spots last season, left Saturday's game with a groin pull. The coaching staff say he'll be ready to go for regular season play against the San Diego Chargers on September 10th, and will likely keep him out of the final preseason game against the Seattle Seahawks to ensure it. 

Nevertheless, a groin injury, especially for a kicker, could continue to nag. If Janikowski isn't ready to go by September, look for backup Eddie Carmona to take over temporarily.
