Nelson was placed on injured reserve Wednesday with a shoulder injury, Matt Schneidman of The San Jose Mercury News reports.

EDGE Analysis

Following his placement on IR, Nelson's 2018 campaign will come to an end. The 34-year-old capped off his 11th season with 25 tackles and two interceptions. Nelson will become an unrestricted free agent following this season.

Nelson (coach's decision) is listed as inactive for Sunday's game against the Colts, Scott Bair of NBC Sports Bay Area reports.

EDGE Analysis

Raiders coach Jon Gruden has elected to list the veteran Nelson as a healthy scratch while Marcus Gilchrist, Erik Harris and Karl Joseph rotate at safety.

Nelson (coach's decision) is not expected to be active for Sunday's game against the Colts, NFL Network's Ian Rapoport reports.

EDGE Analysis

Raiders coach Jon Gruden is expected to bench the 35-year-old veteran in favor of Marcus Gilchrist, Erik Harris and Karl Joseph. The latter trio is slated to rotate at safety while Nelson sticks to the sideline.

Nelson logged three tackles (two solo) and an interception in Sunday's 45-42 overtime win over the Browns.

EDGE Analysis

Nelson notched his first interception of the season while the Raiders defense got torched for 42 points, but Oakland held on thanks in part to four forced turnovers. Nelson could see inflated involvement against the Chargers again in Week 5 if fellow safety Karl Joseph (hamstring) remains sidelined.

Nelson made a season-high five tackles (three solo) in Sunday's 28-20 loss to the Dolphins.

EDGE Analysis

Nelson surprisingly led the Raiders in tackles with only five Sunday, bringing his season total to 11 (nine solo) through Week 3. He may continue to see an increased snap count if fellow safety Karl Joseph remains sidelined by the lower leg injury he suffered during the first half of Sunday's tilt.

Nelson re-signed with the Raiders on Saturday, Ian Rapoport of NFL Network reports.

EDGE Analysis

Nelson was likely brought back in order to help teach defensive coordinator Paul Guenther's system. The 34-year-old has had stints with the Jaguars and Bengals in his 11 year career, and will now be entering his third season with the Raiders. He figures to provide depth in the secondary to go along with his mentoring role.

Nelson racked up 89 tackles (60 solo), five passes defensed, two forced fumbles and one interception in 16 games during his 2017 campaign.

EDGE Analysis

Nelson tied starting middle linebacker NaVorro Bowman for the Raiders' team lead in tackles with 89, though the former appeared in six more games with Oakland throughout the 2017 regular season. Nelson, who will turn 35 years old in September of 2018, is slated to become an unrestricted free agent this offseason. There's a solid chance the Raiders elect to move on from the aging veteran as his abilities in pass coverage continue to regress.

Nelson (illness) is active for Sunday's game against the Chargers.

EDGE Analysis

A late addition to the Raiders' injury report Saturday, Nelson apparently made enough progress in his recovery from the ailment overnight to gain clearance for the regular-season finale. With 82 tackles, an interception and a forced fumble across 15 games this season, Nelson has been able to keep himself on the radar in IDP settings.

Nelson is questionable to play Sunday against the Chargers due to an illness, Michael Gehlken of the Las Vegas Review-Journal reports.

EDGE Analysis

Nelson was a late addition to the injury report Saturday. The Raiders co-captain has 82 tackles this season, his most since 2014, but has just one interception after picking off 13 over the past two seasons.

Nelson logged six tackles (all solo), three passes defensed, one interception and a forced fumble during Monday's loss to the Eagles.

EDGE Analysis

Nelson was finally able to force his first turnover of the season in a pivotal moment during the fourth quarter of Monday's contest, but the Raiders' offense was ultimately unable to capitalize on Nelson's takeaway. Nelson has increased his tackle total from last season, but the 34-year-old safety has regressed in both passes defensed and interceptions.
