The 49ers placed Gonzalez (calf) on injured reserve Tuesday, Adam Schefter of ESPN reports.
Gonzalez sustained a calf injury ahead of Friday's preseason game against the Chargers, and coach Kyle Shanahan recently said the kicker would be sidelined for a few weeks. However, unless Gonzalez is waived with an injury settlement at some point, he'll be forced to miss the 2023 season.
