Justin Skule is back with the 49ers.
The offensive lineman was waived last week with an injury designation, but went unclaimed. He reverts back to the 49ers, becoming their first player on the 2021 injured reserve list.
Skule will not count against the 49ers' initial 90-man roster.
The Vanderbilt product tore his ACL one week ago at practice, the same day safety Tarvarius Moore tore his Achilles.
The 49ers will be on the hook for Skule's $894,000 salary-cap hit after going unclaimed.
Skule, 24, was selected in the sixth round of the 2019 NFL Draft. He played all 16 games last season and started in four. As a rookie, he played in 15 games and started eight.
He was expected to be a key role player in the 49ers' rotation of offensive linemen this season.
