Bengals linebacker Logan Wilson has been diagnosed with a shoulder dislocation (Twitter link via NFL.com’s Ian Rapoport). The injury will take him off the field for some time, according to RapSheet, and his timetable for return remains unclear. 
Wilson had to be carted off on Sunday following a Chargers punt return. Backup Markus Bailey also suffered an injury during the game, leaving the Bengals with just three healthy LBs in Germaine Pratt, Joe Bachie, and Clay Johnston. Fortunately, Bailey will be OK — Rapoport hears that he’s only dealing with a stinger.
Wilson, a second-year pro out of Wyoming, has started in all 12 of his games for the Bengals this year. To date, he’s got four interceptions, one fumble recovery, one sack, and 92 total stops. The advanced metrics at Pro Football Focus have him tied for 47th among all qualified linebackers, good for second on the team behind Pratt (37th).
The Bengals went on to lose 41-22, dropping them to 7-5 on the year. Fortunately for them, the Ravens also lost on Sunday, so they’re just one game back of Baltimore for the AFC North lead. On Sunday, they’ll have a chance to draw closer when they host the 49ers in Cincinnati.
