Jones (undisclosed) was moved to injured reserve Saturday, Cam Inman of the Mercury News reports.
The nature of Jones' injury isn't clear. He's likely stuck on IR through season's end, barring an injury settlement.
Jones played only six games for the 49ers in 2016, recording 17 combined tackles. He was claimed off of waivers by San Francisco last season after Arik Armstead went down with a shoulder injury. Jones will provide depth for the 49ers' defensive line.
The 49ers bring in Jones to bolster their defensive line after Arik Armstead (shoulder) was placed on injured reserve. Jones has been around the league since he was drafted in 2013 but most recently played for the Dolphins, recording seven tackles in seven games before being cut on Nov. 7. The 26-year-old will compete for reps with backup defensive end Ronald Blair behind new starter DeForest Buckner.
The Dolphins waived Jones on Monday, Barry jackson of the Miami Herald reports.
Jones has been on the active roster since Week 2 after originally failing to make the final roster prior to Week 1. He had recorded six tackles in seven games. The Dolphins opted to add secondary depth in their corresponding roster moves.
