Former Arizona Cardinals linebacker Joe Walker has agreed to a one-year contract with the 49ers, the NFL Network reported.

Walker, 27, started 11 games with the Arizona Cardinals last season. He recorded 65 tackles and forced a fumble. Walker was an unrestricted free agent.

Walker entered the NFL in 2016 as a seventh-round pick of the Philadelphia Eagles out of Oregon. In 2018, the Cardinals signed him off the Eagles’ practice squad.
