After a brief stint in Kansas City, D.J. Humphries will return to the NFC West. The longtime Cardinals left tackle is signing with the 49ers, ESPN.com’s Jeremy Fowler reports.

Humphries upped his career start total to 100 through two Chiefs starts, but he ended up giving way to Joe Thuney. The Chiefs kicked their All-Pro left guard outside in an effort to stabilize the position. That plan largely worked out, only for it to be exposed in Super Bowl LIX. The Chiefs have since given ex-49ers swing tackle Jaylon Moore a two-year, $30MM deal; the 49ers will add Humphries from Kansas City as a possible swingman.

The 49ers will hope for a better version of Humphries, as he is now more than a year removed from the December 2023 ACL tear that ended his Cardinals stay. Humphries has battled a host of injuries during his career. In his first Chiefs start, the former first-rounder — given the starting job soon after signing — went down with a hamstring issue. He never reacquired the team’s LT job, only coming in for a Week 18 start that featured the AFC’s top seed resting most of its first-stringers.

Now 31, Humphries profiles as a swing tackle behind starters Trent Williams and Colton McKivitz. The 49ers needed Moore to close out last season, as Williams went down with an ankle injury. Considering Williams is heading into an age-37 season, acquiring a proven backup makes sense for San Francisco. Humphries has only played left tackle since 2017; he and then-Cardinals LT starter flipped sides after the 2016 season. The team had eyed converted guard Spencer Burford as a potential swing option; the fourth-year player will at least have competition for that role now.

The 49ers have not drafted a tackle since taking Moore in the 2021 fifth round. Moore moved up in the pecking order after Mike McGlinchey‘s 2023 Broncos commitment made McKivitz the new right tackle. With Moore now gone — at a price that surprised John Lynch — the 49ers needed a replacement. They have plenty of Humphries intel to go on, with the Lynch-Kyle Shanahan regime having seen the blocker in NFC West matchups from 2017-23.

Humphries’ stay as Arizona’s LT earned him two lucrative deals with the team — in 2020 and ’22. The team cut bait on the three-year, $51MM extension early in Monti Ossenfort‘s GM tenure, having designated him a post-June 1 cut last year. Pro Football Focus graded Humprhies 51st among 81 tackle regulars during a 15-start 2023. While Humphries has dealt with injuries in each of the past three seasons, he missed just one game from 2019-21. The 49ers will hope the 10-year veteran being another year removed from his most serious injury will help him back on track.
