The last major running-back domino has fallen.

After a whirlwind 24 hours of musical chairs, Derrick Henry landed with the Ravens on Tuesday on a two-year, $16 million contract that includes $9 million guaranteed in 2024, according to multiple reports.

The deal has a maximum value of $20 million.

“Flock Nation I swea it’s up ! ????????,” Henry wrote on X after news broke of the signing.

Henry, 30, spent his first eight NFL seasons with the Titans and was one of the best backs in the league over the last six seasons, during which he ran for 8,268 yards and 80 touchdowns.

The four-time Pro Bowler has a lot of miles on his legs, having led the league in carries in four of the last five seasons, but he could be a great fit for a Ravens offense that has found success with a myriad of other running backs in recent years who are less talented than Henry.

After J.K. Dobbins suffered a season-ending injury in Week 1, Gus Edwards carried most of the load out of the backfield, rushing for 810 yards and 13 touchdowns. Keaton Mitchell, Justice Hill and Melvin Gordon were among the other running backs who saw playing time.

Lamar Jackson, of course, led the way with 821 yards rushing en route to his second NFL MVP award.

The Titans decided to sign Tony Pollard to a three-year, $24 million contract to replace Henry.

Edwards struck a deal with the Chargers on Monday.

The rest of the frenetic running-back carousel saw Saquon Barkley go from the Giants to the Eagles; Josh Jacobs from the Raiders to the Packers; D’Andre Swift from the Eagles to the Bears; Devin Singletary from the Texans to the Giants; Antonio Gibson from the Commanders to the Patriots; Austin Ekeler from the Chargers to the Commanders; Joe Mixon from the Bengals to the Texans in a trade; Zack Moss from the Colts to the Bengals and Aaron Jones from the Packers to the Vikings.
