Overview

• San Francisco released Zierer from its practice squad earlier this week following a late-August signing.
• Jacksonville announced his addition to the practice squad in a team statement.
• Zierer had held the 49ers’ International Player Pathway slot, which the team reassigned to Isaac Alarcon.
• The IPP designation does not count against the practice-squad limit, and Alarcon had recently served a six-game NFL suspension for a drug-policy violation.
• Before landing in Jacksonville, Zierer had brief 2025 stints with the Falcons and Browns and spent 2023–24 on the Texans’ practice squad.
