Despite the Raiders' emphasis on adding pass rushers already this season, their efforts continue. They are reportedly hosting free agent pass rushers Rob Jackson, and Alex Carrington this week according to Vic Tafur of the San Francisco Chronicle. Carrington is on his visit today with Jackson to arrive today or tomorrow.

The Raiders have already signed Justin Tuck and Lamarr Woodley as the starters at the two defensive end spots. They also added Antonio Smith to play defensive tackle.

The 6-5, 284 pound Carrington has played four seasons with the Bills after they chose him with a third round pick in the 2010 draft. He had started the first three games of last season before being lost for the season with a torn quad. Though he has started just nine games in his career, he appeared in nearly every game over the 2011 and 2012 seasons. He has just 4.0 career sacks. His best season was 2012 in which he lad 15 quarterback hurries and 2.0 sacks with 19 tackles (12 solo).

The 6-5, 284 pounder is a versatile defensive lineman who can play inside in a 4-3 and as a defensive end in 3-4 alignments.

Jackson is a 3-4 outside linebacker who was stuck behind starter Brian Orakpo in Washington. He is also seen as a player who can player either defensive end or linebacker.
