Bailey has been suspended four games for violating the NFL Policy and Program for Substances of Abuse.
With Bailey -- who has recorded 12 catches for 182 yards and a touchdown in eight game to date -- set to miss time, it's now understandable that the Rams are expected to work out wideouts Hakeem Nicks, Wes Welker and Vincent Brown, per ESPN's Adam Caplan.
Keenum (concussion) is inactive Sunday against the Bengals, ESPN's Nick Wagoner reports.
Keenum was limited in practice all week while going through concussion protocol, and all indications leading up to the Sunday matchup had suggested Nick Foles would re-take the reins at quarterback. Keenum didn't necessarily "wow" anyone last week after completing 46 percent of his passes for 136 yards and a score, but had been expected to be the starting quarterback if healthy. Foles will now get another chance after nine underwhelming performances, but whoever claims the full-time job moving forward will likely be limited by the St. Louis run-first offense.
Quinn (hip) in inactive Sunday against the Bengals, ESPN's Nick Wagoner reports.
Quinn has sat out two of the past three games, and was on the field for just 14 snaps Week 10 against the Bears. After missing practice all week, it's not overly surprising to see him sit, as the Rams may want to save him to help compete for a Wild Card spot during the season's final stretch. His absence is certain to adversely affect the St. Louis pass rush.
Zuerlein (groin) is inactive Sunday against the Bengals, ESPN's Nick Wagoner reports.
Zuerlein was a late addition to the injury report after suffering a groin injury during Friday's practice, and that ailment turned out to be enough to hold him out of action. According to the Rams' official site, the recently-signed Zach Hocker will get the starting nod at kicker Sunday afternoon.
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.
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.
