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.
Head coach Jeff Fisher reiterated Sunday that Keenum will start when he receives clearance from the concussion protocol, Nick Wagoner of ESPN.com reports.
Keenum fulfilled expectations with inactive status Sunday at Cincinnati, forcing the inimitable Nick Foles to carry the offense to the tune of 30-for-46 passing, 228 yards, and no touchdowns versus three interceptions. Still in the midst of the protocol for head injuries, Keenum's activity level in practice this week will forecast whether he's nearing a return.
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.
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.
