The Ravens re-signed undrafted rookie linebacker Andrew Bose on Wednesday, the team said on its website.
In a corresponding roster move, the club waived rookie linebacker Trey DePriest, who played collegiately at Alabama.
A Rhode Island product, the 6-foot-2, 232-pound Bose was credited with 125 tackles (48 solo) in his final collegiate season in 2014. He also recorded 4.5 sacks and one interception.
The 21-year-old Bose signed with Baltimore on May 8 before being waived six days later.
The Ravens have filled all 90 roster spots. The club is holding organized team practice activities this week.
