Cincinnati Bengals linebacker Dontay Moch has been suspended for the first four games of the 2012 season for a violation of the NFL's banned substance policy, according to Jason LaCanfora of CBS Sports.

Moch missed all of his rookie season with a foot injury after being a third-round pick.

According to LaCanfora, Moch is expected to appeal the ruling on the suspension.
