Carolina Panthers backup running back Mike Goodson has been traded to the Oakland Raiders for backup offensive lineman Bruce Campbell.

General manager Reggie McKenzie added two more pieces of the puzzle to the 2012 Raiders on Friday, reaching a deal with unrestricted free agent linebacker Philip Wheeler after earlier in the day acquiring running back Mike Goodson from the Carolina Panthers in exchange for offensive lineman Bruce Campbell.

The Raiders announced Wheeler's signing via Twitter on Friday night. Wheeler, who visited the Raiders facility Thursday, will be penciled in as the starting strong side linebacker following the loss of Kamerion Wimbley in free agency.

Wheeler had 84 tackles, 47 unassisted as the starting string sideline backer for Indianapolis last season.

Goodson, 24, helps fill the void of two running backs who left in free agency, serving as a complementary running back in place of Michael Bush and as a special teams performer to compensate for the loss of veteran Rock Cartwright.

Goodson, buried on the depth chart behind DeAngelo Williams and Jonathan Stewart, was also hobbled by hamstring pull last season. In 2010, Goodson rushed for 452 yards in a reserve role and is a regular on all four special teams.

"Being behind DeAngelo and Stewart for a couple of years has been difficult just wanting to play and being a competitor,'' Goodson said. "I wasn't looking to leave, but anywhere that gave an opportunity I'm definitely up for that.''

Goodson is looking forward to help back up Darren McFadden along with second-year man Taiwan Jones and feels his style is well-suited to the Raiders' zone blocking scheme as imported by offensive coordinator Greg Knapp from the Houston Texans.

"I've always been a fan of that offense, one cut and you get up field,'' Goodson said. "You don't have a lot of moves in the backfield, you kind of just getting going and use your speed."

The Raiders selected Campbell in the fourth round of the 2010 draft.
