49ers Release Isaac Alarcón After Six-Game Suspension

The move follows a six-game ban for violating the NFL’s substances policy.

Overview

  • The 49ers confirmed Alarcón’s release in Monday’s official transactions, ending his practice-squad stint after time on the reserve/suspended list since August.
  • Alarcón entered the league through the International Player Pathway in 2020, spent three seasons on the Cowboys’ practice squad, and signed with San Francisco in 2024.
  • He has never appeared in a regular-season NFL game and logged one preseason appearance for the 49ers, playing 29 snaps against the Broncos.
  • San Francisco also released offensive lineman Killian Zierer from the practice squad in the same set of moves.
  • The roster change could provide flexibility as the 49ers manage offensive-line depth, with potential openings tied to injured players such as Ben Bartch or Spencer Burford.
