San Francisco signed Hollman to a reserve/future deal Wednesday, Nick Wagoner of ESPN.com reports.
A sixth-round selection of the Packers in 2019, Hollman appeared in 18 games across his first two NFL seasons before being dealt to the Texans ahead of the 2021 campaign. Hollman couldn't crack Houston's roster and ultimately found his way to the Giants' practice squad. He'll now look to carve out a role with the 49ers in 2022.
