Head coach Kyle Shanahan told reporters Monday that Jackson (knee) isn't expected to return during training camp, Lindsey Pallares of the 49ers' official site reports.
Jackson was moved to the active/PUP list last week after missing the final 12 games of the 49ers' 2023 campaign due to a knee issue. There's no timetable on Jackson's return, but it appears that he's definitely still hindered by his injury. Once the 23-year-old gets back on the field, he's expected to compete for a depth role on San Francisco's defensive line.
