Outside linebacker Tamba Hali (knee) did not practice Thursday, according to the team's injury report.
Hali, who did practice on Wednesday, dealt with a balky knee all of last season, when he finished with six sacks and earned his fifth Pro Bowl berth.
Though five games this season, Hali has recorded 10 combined tackles and one sack.
Also, nose tackle Dontari Poe (high ankle sprain) and inside linebacker Josh Mauga (groin/Achilles) each missed practice for the second straight day. Both are starters.
No. 4 tight end Brian Parker (finger) was added to the injury report Thursday, but was a full participant.
