DL DJ Jones
Losing Jones to a high ankle sprain in Week 14 was an under-the-radar tough injury for the 49ers’ defensive line. The 2017 sixth-round pick emerged as the starting nose tackle in 2019. He’s a strong run defender who also flashed some explosiveness as a pass rusher with the first two sacks of his career. Jones should be back in plenty of time for the start of the year, and his presence in the middle of the defensive line will be a significant upgrade over what the 49ers finished the 2019 campaign with.
