Cincinnati Bengals linebacker Dontay Moch has been suspended for the first four games of the 2012 season, says Aaron Wilson of Scout.com.

The reason for the suspension was not disclosed, but a source indicated to Wilson that it was a violation of the NFL's substance abuse policy.

Moch broke his foot and missed virtually all of his rookie season with the Bengals.
