Patterson signed a contract with the Raiders on Monday, Vic Tafur of the San Francisco Chronicle reports.
Patterson spent the first four years of his career in Minnesota, although high expectations for the athletic receiver were never met after a rookie season where he compiled a career-best 469 receiving yards and nine total touchdowns. At 25 years old, Patterson initially slots into the No. 4 spot on the depth chart behind Seth Roberts, but it's not a foregone conclusion that Roberts will remain ahead of Patterson when the 2017 campaign ultimately kicks off. Additionally, Patterson will likely serve as the team's top kick returner moving forward.
