Rams add DT Matt Conrath to injury report

EARTH CITY, Mo. -- The St. Louis Rams' added defensive tackle Matt Conrath to their injury report on Thursday.

Conrath apparently suffered a concussion and was limited in practice. The Rams normally have plenty of depth on the defensive line but if Conrath is unable to play Sunday, they could be a bit thin on the interior.

Do-everything lineman William Hayes is nursing a knee injury and normally plays inside and out. If both he and Conrath are unable to go, the Rams would be down to Jermelle Cudjo and the versatile Eugene Sims as options behind the starters. Of course, there's still plenty of time for Conrath to pass the necessary tests and return. Hayes, however, appears unlikely to be ready this week.

The rest of the Rams' injury report reads the same as it did Wednesday.

Did not practice: RT Rodger Saffold (knee), Hayes (knee), CB Cortland Finnegan (thigh), CB Trumaine Johnson (illness)

Limited participation: Conrath (concussion), CB Brandon McGee (thigh), LB Will Witherspoon (thigh)
