The 49ers head into this weekend's matchup with the Oakland Raiders with various players looking to either secure a roster spot or even secure a starting spot. Two players with a lot to gain on Saturday are wide receiver Kyle Williams and cornerback Tramaine Brock. They're getting additional playing time in part because of injuries ahead of them and both are taking advantage of the opportunities.
Kyle Williams did not start last Friday but came on late in the first half, potentially earlier than he would have if Michael Crabtree was in the playing rotation. He caught two passes for 34 yards, but potentially more important were two big blocks he made on defensive end Turk McBride. One of the blocks resulted in a penalty for an illegal block in the back, but for the most part, throwing himself around like that will only improve his stock with the coaching staff.
Williams' issue thus far in his brief NFL career has been staying healthy. His rookie season was marred with a variety of injuries that kept him inactive a little too frequently. If he can stay healthy in his second season, he could very well break through with more regular playing time and solid production.
On the defensive side of the ball, Tramaine Brock has received a boost in playing time due to Shawntae Spencer's nagging hamstring injury. Brock got the start last Friday over rookie Chris Culliver and with Spencer missing practice this week, Brock could find himself starting once again. Brock entered camp as a bubble guy thanks to the additions of Carlos Rogers and Chris Culliver. By making his way into the starting lineup he's obviously made an impression on the coaching staff. A strong performance this Saturday could go a long way for Brock.
