The Ravens got undrafted rookie tight end Jacob Breeland back on the reserve list (non-football injury) after he cleared waivers.
Baltimore waived Breeland Wednesday and hoped to bring him back so he could contribute when ready.
Breeland is trying to come back from a season-ending knee injury suffered last season on Oct. 11. He was off to a hot start with six touchdowns in Oregon's first six games.
However, the COVID-19 pandemic has made rehab more difficult this offseason for rookies because they were not permitted in team facilities.
The Ravens also have undrafted rookie tight end Eli Wolf and signed veteran Jerell Adams this week. They, along with Charles Scarff, will compete for the third tight end spot behind Mark Andrews and Nick Boyle.
Undrafted defensive back Nigel Warrior was moved to the active roster when Breeland was waived.
