The 49ers’ injury report from Thursday’s practice looks only slightly different than Wednesday’s. The only changes to it are positive on the injury front for San Francisco heading into their crucial Week 14 visit to New Orleans to take on the No. 1-seed Saints.

Wide receiver Dante Pettis missed practice Wednesday with a knee injury he suffered in practice leading up to the team’s Week 13 loss to the Ravens. He was inactive vs. Baltimore, but his return to practice Thursday could signal that the second-year receiver will be available vs. New Orleans.

A glaring difference was Arik Armstead’s absence Thursday after a full Wednesday practice. The team’s leader in sacks missed the session for a veteran’s day off. There was no injury, and there’s no doubt about his availability Sunday.

Defensive tackle DJ Jones also got a full session in after limited participation Wednesday. He sprained his ankle against the Ravens and was considered day-to-day to start the week. Thursday’s practice indicates Jones will be ready to play Sunday, although his status won’t be determined until after Friday’s practice.
