Update: The 49ers officially announced the signing on Friday, August 7.
Both players reportedly visited this week to undergo physicals and COVID-19 testing.
The Dolphins drafted Jordan out of Oregon with the No. 3 overall pick in 2013. He spent two seasons with the Seahawks before joining the Oakland Raiders in 2019.
Jordan, 30, registered five tackles, two sacks, and a pass defensed through seven games with the Raiders in 2019. He had 13 quarterback pressures in 113 pass rush attempts, according to Pro Football Focus.
Jordan has recorded 91 tackles, 10.5 sacks, five passes defensed, and two forced fumbles through his five NFL seasons, not counting 2015. He missed that season due to a suspension for violating the NFL's performance-enhancing substance policy.
