49ers sign DE Arden Key to one-year deal

The 49ers are adding depth pieces on offense and defense Wednesday afternoon. Shortly after their Wayne Gallman agreement surfaced, Ian Rapoport of NFL.com reports San Francisco agreed to terms with Arden Key.

Like Gallman, Key visited the 49ers this week. Formerly an Oakland Raiders third-round draft choice, the three-year defensive end contributor will head back to the Bay Area on a one-year deal.

The Raiders waived Key last week, doing so after adding former 49ers defensive end Solomon Thomas in free agency. The 49ers lost Thomas and Kerry Hyder, who signed with the Seahawks, and injuries significantly affected their defensive end group last season. Both Nick Bosa and Dee Ford missed most of the season. Key may be in position to see frequent time.

While Key went in the 2018 third round, he was viewed as a possible first-round pick at one point. The LSU product registered 11 sacks as a sophomore in 2016. While he has not produced much as a pro (three sacks in three seasons), Key did post 11 quarterback hits last season as a Raider reserve. Next season will be Key’s age-25 campaign.
