The Kansas City Chiefs are getting some help along their offensive line.

Free agent tackle D.J. Humphries is signing with the Chiefs, a person with knowledge of the deal told USA TODAY Sports. The person spoke on the condition of anonymity because the deal is not yet official.

Humphries’ deal is worth a max value of $4.5 million for the rest of the season.

The former Arizona Cardinals tackle has been medically cleared from an ACL injury he sustained last season.

Humphries received interest from other teams but chose the reigning Super Bowl champions.

The 6-foot-5 tackle was originally a 2015 first-round pick by the Cardinals. He started all 98 games he played for Arizona.

How D.J. Humphries fits in Kansas City

The Chiefs are getting a perennial starter at tackle, but Humphries has battled injuries and is coming off an ACL tear.

Humphries, who turns 31 next month, was a Pro Bowler in 2021.

The Chiefs have had issues at left tackle this season. Rookie Kingsley Suamataia was the starter to begin the year but was benched after Week 2. Wanya Morris replaced Suamataia at left tackle, however, he’s had inconsistent performances as well.

Humphries could stabilize Kansas City’s left tackle position if he can regain his pre-injury form. The fact he’s medically cleared from the knee injury is a positive sign and makes this move worth the gamble.

The 9-1 Chiefs will face the 3-7 Carolina Panthers on Sunday.
