The Rams rewarded Alaric Jackson this offseason, giving him a big-ticket deal to complete a transition from UDFA to cornerstone left tackle. The recently paid blocker, however, has seen a blood clot issue resurface.
Jackson is navigating a blood clot for the second time as a pro, NFL.com’s Ian Rapoport reports. The Rams believe he will play this season, but they added D.J. Humphries on Thursday as an insurance measure.
A 2022 season that featured just about every Rams O-line starter (and a few backups) go down involved Jackson missing much of it with blood clots. Jackson, who started six games in 2022, missed the Rams’ final nine games due to the blood clot development. The Iowa alum returned in 2023 and beat out Joe Noteboom for Los Angeles’ left tackle job, transforming his career en route to the payday this offseason. But this familiar concern changes the Rams’ outlook on Matthew Stafford‘s blind side.
Joining Ronnie Stanley as a prime left tackle target who did not make it to free agency, Jackson re-signed with the Rams shortly after the team regrouped with Stafford. Both pillars had neared the 2025 league year as question marks, with the Rams allowing their quarterback to talk to other teams. Days before free agency, however, they confirmed another Stafford rework would be completed and then came to terms with Jackson on a three-year, $57.75MM deal that came with $30MM guaranteed at signing.
A Tristan Wirfs bookend at Iowa, Jackson has been a Rams priority for a bit now. They placed a second-round RFA tender on the 2021 find last year, but he missed the first two games of last season due to a suspension under the personal conduct policy. Jackson, 27 in July, returned to play in the team’s next 14 games and receive a top-20 tackle grade from Pro Football Focus. The Windsor, Ontario, native having dealt with this issue before brings an obvious concern, especially as the Rams have seen longtime right tackle Rob Havenstein navigate injury trouble last season.
The longest-tenured Rams performer (as the team’s final link to its St. Louis years), Havenstein missed six games last season. As a result, the 10-year veteran underwent cleanup surgeries on both shoulders this offseason. Havenstein, 33, is expected to be ready for training camp. The team, though, already appeared thin at tackle prior to the Humphries signing. Another Jackson hiatus certainly would deal a significant blow.
While Jackson’s first bout with blood clots came as the Rams’ 2022 Super Bowl title-defense season had already drifted off track, his second affects a much better team. Humphries was part of the Chiefs’ title-defense season last year, but the longtime Cardinals LT did not make it through his first game without an injury intervening. Dealing with many maladies during his career, Humphries saw his rehab from ACL surgery precede a hamstring issue that surfaced his Kansas City debut.
The Chiefs did not give the former first-rounder his job back, sliding left guard Joe Thuney to LT. The team then moved on during the offseason, but Humphries suddenly slides back into a key position with a contending team — one that did not draft a tackle in April.
