Jackson (calf) has been ruled out ahead of Sunday's game against the Panthers, Jeff Nowak of Audacy Sports reports.
The Appalachian State product failed to participate in any practice this week due to a calf injury, so being ruled out for Week 1 comes as no surprise. With Jackson, Jaylan Ford (hamstring) and Nephi Sewell (knee) all sidelined Sunday, Anfernee Orji remains the only reserve inside linebacker on the Saints' roster.
