Losing one cornerback is bad luck. Losing two cornerbacks, starting cornerbacks, is a fluke. Losing ten cornerbacks in a single season, well, someone should probably call Ripley's. The St. Louis Rams added Marquis Johnson to the injured reserve list today, per Howard Balzer. He is the tenth cornerback the Rams have lost this season and the sixth corner currently on injured reserve. 

Johnson suffered an abdominal bruise against Seattle last week. He spent Monday in the hospital for observation, but apparently the prognosis wasn't good enough for him to get back on the field this season. Johnson ended up on IR last year; he's played a total of five games since being drafted in the seventh round of the 2010 NFL Draft. 

Cornerback Kendric Burney, a rookie out of North Carolina, was added to the practice squad today as well, the unlucky bastard. Burney was in for a tryout last week. Small and not particularly fast, Burney is more of a slot, nickel corner who can play the ball fairly well. Johnson had been working as the Rams nickel since his return from the PUP list earlier this month.

The Rams will have to add another corner to the 53-man roster to replace Johnson.
