Schreck injured his knee during the Bengals' preseason contest Sunday, Jim Owczarski of The Cincinnati Enquirer reports.
The severity of the injury is unclear at this point. Knee injuries can fall within a wide range of diagnoses, so we'll have to wait until more information becomes available to establish a timeline for his return. Being that he's buried on the team's depth chart at tight end, Schreck could be on the outside looking in if it takes him a long time to get back.
