Fumagalli and the 49ers agreed on a one-year contract Monday, Matt Maiocco of NBC Sports Bay Area reports.
Fumagalli was cut from the 49ers' practice squad in November, but he'll now return to the organization ahead of the 2023 campaign. The tight end hasn't appeared in a game since 2020, when he participated in eight contests with the Broncos, catching eight passes for 80 yards and a touchdown.
