Bennett (ribs) was ruled out for Thursday's game at Green Bay.
Bennett turned in limited practices both Tuesday and Wednesday, likely in order to test out his injured ribs, but the Bears will opt for caution and rest the tight end on a short week. In his stead, Zach Miller should have an ample workload, which could expand further if Alshon Jeffery (groin/shoulder) and Matt Forte (knee) are eventually ruled out.
Rolle (knee) is not expected to play in Thursday's game against the Packers, ESPN.com reports.
Rolle missed Sunday's game against the Broncos after injuring his knee during Saturday's walkthrough. Chris Prosinski figures to start for a second straight week, following a six-tackle, one-sack showing Sunday afternoon. He's a better IDP option than rookie free safety Adrian Amos, who has just 39 tackles this season despite starting every game.
Royal (knee) was ruled out for Thursday's contest at Green Bay.
Royal will miss his fourth consecutive game due to a knee injury, which he suffered in Week 8. With Martellus Bennett (rib) also sidelined, and Alshon Jeffery (groin/shoulder) and Matt Forte (knee) questionable Thursday, the Bears may again trot out Marquess Wilson (groin) as the No. 1 wide receiver.
Brooks (personal) returned to the field Thursday, recording five tackles (two solo) and a pair of sacks in the loss to Seattle.
Brooks had missed last week's contest to attend the funeral of his sister. He returned Thursday and the extra rest seemed to have given the veteran linebacker a boost. While this was a monster game, it has to be taken with a grain of salt, as the Seattle offensive line is, well, offensive.
Celek (ankle) has been ruled out of Sunday's game against the Cardinals, Cam Inman of the San Jose Mercury News reports.
Celek initially left the field with a leg injury, which was clarified as an ankle concern. Currently, the severity of the ailment is unknown, but the 49ers will likely lay out a return timetable in due time.
Hyde (foot) has been ruled out for Sunday's game against the Cardinals, CSN Bay Area reports.
Hyde still hasn't played since Week 7 and is no lock to suit up again this season. Shaun Draughn will continue to lead the San Francisco backfield, with Kendall Gaskins and Travaris Cadet working in reserve. Draughn played nearly all of the offensive snaps in Week 11 against the Seahawks.
Smelter (knee) is slated to practice this week, the San Jose Mercury News reports.
Smelter will remain on the 49ers' Reserve/Non-Football Injury list for now, as the team has a three-week window in which to evaluate whether or not to officially add the wideout to the team's 53-man active roster.
