Linebacker Paul Worrilow, signed by the Baltimore Ravens on Friday, told coach John Harbaugh on Saturday that he is retiring.
Worrilow, 29, missed last season with the Philadelphia Eagles because of a torn ACL. The Eagles released him earlier this month, and the Ravens picked him up to provide depth at the position.
"I spoke to him last night, and he was great -- all ready, excited to go, so I was surprised, you know," Harbaugh told reporters on Saturday. "I assume he's trying to figure things out, work things out, what he wants to do, he and his family. Every person has a right to do that."
Worrilow was an All-American at Delaware and signed in 2013 as an undrafted free agent with the Atlanta Falcons, where he spent four seasons. He moved on to the Detroit Lions in 2017.
In his career, he has 413 tackles, four sacks, two interceptions and three forced fumbles in 72 games (52 starts).
