The Raiders confirmed Tuesday that they'll shut LB Denzel Perryman for the final 2 games after he dislocated his left shoulder in Saturday night's loss at Pittsburgh. Undrafted rookie Luke Masterson looks like the best bet to lead Vegas LBs in playing time after seeing 84% playing time against the Steelers. Masterson has delivered 10+ tackles in 2 straight contests, so he'll carry tackle upside Sunday against the 49ers.
