The Raiders traded wide receiver Louis Murphy to the Panthers for an undisclosed conditional draft pick.
Murphy has 90 career receptions for 1,371 yards and six touchdowns in three seasons since being a fourth-round pick out of Florida. However, he posted career lows of 15 catches for 241 yards and no touchdowns in 11 games last season.
Whether Murphy's roster spot would've been at risk in training camp was open to debate. The Raiders are counting on a young trio of receivers -- Denarius Moore, Darrius Heyward-Bey and Jacoby Ford -- and raved about the offseason performance of rookie Juron Criner.
Carolina earlier shipped running back Mike Goodson to Oakland earlier this offseason for offensive lineman Bruce Campbell. That March 30 trade was made because the Raiders were looking for a backup behind Darren McFadden after Michael Bush left Oakland in free agency, signing a four-year, $13 million deal with the Bears.
The Panthers have no proven options behind Steve Smith at wide receiver. Brandon LaFell, a third-round pick in 2010, had 36 catches for 613 yards and three touchdowns last season and is the probable starter opposite Smith.
David Gettis is also expected to be in the mix to battle for the starting spot opposite Smith.
