What happened: The Reserve/Injured designation carries a minimum four-game absence. Harrison was the 27th overall pick in the 2023 NFL Draft out of Oklahoma and has held left tackle since his rookie season.

Why it matters: Losing the blind-side starter forces a reshuffle up front during the regular season. The same Anton Harrison who has started since 2023 leaves a continuity gap at a premium position.

What to watch: Jacksonville's next game will reveal who fills left tackle for the mandatory absence.
