Board agreed to a contract with the Ravens on Tuesday, Ryan Mink of the team's official site reports.
Board, who spent his first four NFL campaigns with the Ravens after signing with the team as an undrafted free agent in 2018, is coming off a 2023 regular season in which he recorded 10 tackles with the Patriots. In his looming return to Baltimore, the 28-year-old will bolster the depth of the team's linebacking corps while also maintaining his role as a core special-teams contributor.
