San Francisco 49ers Release Mexican Offensive Lineman Isaac Alarcón Ahead of NFL Season

Roster Cuts and the International Practice Squad Exception

However, the offensive lineman avoided leaving the organization entirely when San Francisco re-signed him to their practice squad.

The move was facilitated by the IPPP exemption, a mechanism that permits the 49ers to carry 17 players on their practice squad rather than the standard 16-player maximum. Alarcón originally entered the league as the inaugural Mexican player assigned via the international program, spending his initial seasons with the Dallas Cowboys before moving to the Bay Area in 2024.

Preseason Performance and Lingering Challenges

During the lead-up to the roster cuts, Alarcón featured in San Francisco’s final preseason matchup against the Las Vegas Raiders.

The latest transaction follows a turbulent period for the offensive lineman.

Implications for a Potential Regular Season Debut

Despite logging years within NFL systems, Alarcón has yet to make his regular-season debut. Remaining on the practice squad preserves his availability as immediate depth should injuries impact the 49ers’ offensive line during the grueling 17-game campaign.

Furthermore, retention in San Francisco keeps the lineman positioned for potential international visibility. The 49ers are scheduled to play a regular-season fixture against the Minnesota Vikings on November 22 at the Estadio Azteca in Mexico City. A promotion to the active roster prior to that matchup would give the 28-year-old blocker a chance to play a meaningful snap in his home country.

Next Steps for the 49ers

San Francisco continues its preparations for the opening week of the NFL regular season with Alarcón working out of the practice squad. Official injury reports and practice squad elevations ahead of Week 1 will clarify whether the team opts to bring any developmental trench depth to the active roster.
