Vincent Brown

The Oakland Raiders, looking to bolster their wide receiving corps, signed fourth-year pass catcher Vincent Brown to a one-year deal, multiple sources told FOXSports.com.

Brown, who was released by the San Diego Chargers last month, worked out for the team Monday morning and passed a physical.

Rehabbing from a calf injury, Brown could be the jolt Oakland's offense needs. Brown was selected in the third round of the 2011 NFL Draft and hauled in 41 receptions for 472 yards last season.

Brown was unimpressive last year as the Chargers WR2 opposite of Keenan Allen, who emerged as a rookie.
