Jaguars place left tackle Anton Harrison on injured reserve with knee surgery timeline unclear

The Jacksonville Jaguars moved quickly to formalize a significant injury on Tuesday, placing left tackle Anton Harrison on injured reserve. The team indicated Harrison is headed for arthroscopic knee surgery, and it will not be until after the operation that a more precise return timeline can be established.

According to the report circulating Tuesday, the Jaguars also communicated that Harrison will be sidelined at least four games regardless of what the surgery ultimately determines. That minimum absence has immediate roster implications, because the left tackle spot is a foundational role in protecting the quarterback and setting the edge in the run game.

The report further notes that one possible outcome is that Harrison could miss the rest of the season. While that is not a guaranteed end point, the phrasing underscores the uncertainty that can follow knee injuries that require surgery rather than a simple recovery protocol.

From a team-building standpoint, an injured reserve designation often shifts urgency to two places at once. First, Jacksonville must stabilize the offensive line for the coming week-to-week stretch while Harrison cannot practice or play. Second, the Jaguars likely have to lean more heavily on depth options at tackle or reconfigure the line to maintain protection continuity.

For the player, injured reserve also changes the rhythm of a season. Instead of preparing week to week, Harrison’s focus turns to recovery and rehabilitation following surgery, with progress monitored as doctors assess the knee after the procedure and as his conditioning builds back toward game readiness.

What to watch next is how the Jaguars respond on the field in the next few games, particularly whether they keep the offensive line stable with internal adjustments or use a more notable shift across positions. Also watch for any further clarification from the team as the surgery takes place and as Jacksonville updates the next stage of Harrison’s timeline.
