The Saints won't have defensive end Chase Young for a second consecutive game.
Young injured a calf during practice in the Sept. 3 practice and has not practiced since.
He played all 17 games last season.
The Saints also ruled out safety Julian Blackmon (shoulder) and offensive guard Trevor Penning (toe). Neither practiced this week.
Offensive tackle Taliese Fuaga (knee) remained limited in Friday's practice and is questionable. He did not practice Wednesday.
49ers wide receiver Jauan Jennings (shoulder) returned to a limited practice Friday.
The team lists him as questionable to play Sunday against the Saints.
Jennings left with his injury in the fourth quarter of the 49ers' win over the Seahawks and did not return. MRI and CT scans revealed no significant damage to his left shoulder.
He did not practice Thursday or Friday.
Left tackle Trent Williams also is listed as questionable after limited work Friday. The 49ers listed him as knee/not injury related earlier in the week, but he now has only the knee listed.
He did not practice Wednesday or Thursday.
The 49ers officially ruled out quarterback Brock Purdy (left shoulder, toe).
Running back Christian McCaffrey (calf/not injury related) does not have an injury designation after another full practice.
The Texans could have their starting right guard back for Monday night's game against the Buccaneers.
Ed Ingram returned to a full practice Friday.
He popped up on the injury report Sept. 4 with an abdomen injury. He did not play Sunday and continued his limited participation in practice Thursday, his third consecutive practice without full participation.
If Ingram plays, the Texans will shift Tytus Howard back to right tackle from right guard and rookie Aireontae Ersery back to left tackle from right tackle.
Center Jake Andrews (high ankle) did not practice again and is not expected to play this week. He left Sunday's game after 45 snaps, and Jarrett Patterson replaced him.
It does not look like the Texans will have starting wide receiver Christian Kirk and primary return specialist Braxton Berrios again this week. Both remained out of practice Friday with hamstring injuries.
