The Raiders made another addition to their receiver group Friday, signing free agent J.J. Nelson.

Nelson, 26, spent the last four seasons with the Cardinals. He had career-highs of 34 receptions, 568 yards and six touchdowns in 2016, but had just seven catches for 64 yards last season.

Nelson, listed at 5-foot-10 and 160 pounds, has averaged 17.8 yards per reception since joining the league in 2015 - the highest average among players with at least 80 catches in that span.
