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

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

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

Nelson logged five tackles (three solo) during Sunday's 34-14 loss to the Bills.
Nelson has racked up 44 tackles through eight games this season, but the Raiders' starting free safety has yet to force a single turnover.

Nelson will look to snag the first interception of his 2017 campaign in Week 9 against the Dolphins, who plan to be led by quarterback Jay Cutler (ribs).
Nelson racked up eight tackles (six solo) Thursday against the Chiefs.
This was Nelson's third game with eight tackles, but unlike the past two seasons when he accumulated a combined 13 interceptions, he has yet to snag a pick this campaign. He still makes enough tackles to be a mediocre IDP threat, but he'll need to make some interceptions before he can be considered high-caliber.
Nelson racked up eight tackles (five solo) and one pass defensed during Sunday's win over the Titans.
Nelson was the second-leading tackler for the Raiders on Sunday, while fellow safety Karl Joseph led the way with nine. Oakland's secondary, which disappointed in 2016, played well enough in Week 1 to limit Titans quarterback Marcus Mariota to no completion longer than 24 yards and zero passing touchdowns. Nelson and crew have a much easier matchup in Week 2 against a lousy Jets offense led by QB Josh McCown.

Nelson will finish his 2016 campaign with 65 tackles, 12 passes defensed, five interceptions, and two fumble recoveries in 16 games. He took a step back in terms of his production following a stellar year with the Bengals in 2015, but he still provided value as the Raiders' top free safety. The 33-year-old has one more year left on his contract with Oakland, so he has plenty to play for in the upcoming playoffs.

Nelson reeled in an interception to go along with one tackle (one solo) and one pass defensed during Sunday's victory over the Jaguars.
Nelson and the rest of the Raiders' defense saw improvements in Week 7 after a bit of a horrid start to the season, although they were up against a downward-spiraling Jaguars offense on Sunday. Nelson recorded a season-low in tackles this past week, but will look to get back on track in that department Week 8 against the Buccaneers.
Nelson made six tackles (four solo), one interception, two passes defensed, and a fumble recovery during Sunday's win over the Titans.
Nelson brought in his first interception of the 2016 regular season in Week 3 as the rest of the Raiders' defense also took a step forward, limiting the Titans to just 10 points.

Nelson recorded eight tackles (seven solo) during Sunday's Week 1 win over the Saints.
Nelson tied linebacker Malcolm Smith for the most tackles by any Raider on Sunday, while the team's defense got torched by Drew Brees and the Saints' receivers.

Nelson and the rest of the secondary will look to improve when they host the Falcons in a Week 2 matchup.
