Originally drafted No. 3 overall by the Miami Dolphins in 2013, Jordan spent the 2019 season with the then-Oakland Raiders, racking up two sacks.
The pass-rusher spent the prior two years with the Seattle Seahawks. Jordan was suspended for all of 2015 due to a violation of the performance-enhancing substance policy and also sat out the following season before being released by Miami in 2017.
The 49ers have formed a dominant defensive line that contains other first-round talents Nick Bosa, Arik Armstead, Dee Ford, and Javon Kinlaw. Jordan will likely fight it out in training camp for a backup role.
