Tramaine Brock and Chris Culliver are both officially listed as questionable for Sunday's home opener in Levi's Stadium. Right tackle Anthony Davis, who has not practiced for two weeks, is also listed as questionable while working his way back from a hamstring injury.
Brock left last week's win over the Cowboys in the first quarter with a sprained big toe and did not practice all week. Culliver also left the game early with a concussion and did not return.
Culliver was limited in practice this week, wearing a blue no-contact jersey. He must pass the league's mandated concussion protocol in order to play, including a contact test Saturday. Head coach Jim Harbaugh anticipates Culliver will be available.
"Right on schedule. Should be good to go," said Harbaugh.
With Brock out, the likely candidate to replace him on the right side would be Perrish Cox, who did so last week in Dallas.
"No sense to say exactly our next plan would be," Harbaugh said.
Safety Eric Reid said earlier in the week he anticipates Chris Cook will also be dressed Sunday after being inactive last week against the Cowboys. Cook has made four starts against the Bears during his time with the Vikings, including two last season. He allowed a pair of touchdowns and 132 yards in coverage of Jeffery in Week 13, per Pro Football Focus.
The 49ers will have Jimmie Ward available after doctors ruled he did not suffer a concussion late in the win over the Cowboys. Dontae Johnson, who had two pass breakups Sunday, will also be available.
Davis practiced for a week toward the end of preseason before suffering a set back with a hamstring injury. He missed practice during the offseason program and training camp while recovering from shoulder surgery for an injury suffered early last season. Jonathan Martin played well in his place in Dallas.
