CLEVELAND — Joe Haden’s case remains mysterious and unresolved.

The Browns cornerback, and one of Cleveland’s best players, is awaiting word from the NFL on a possible four-game suspension for failing a drug test. On Tuesday, Browns president Mike Holmgren revealed in a local radio interview that Haden has already had his appeal hearing with the league.

Holmgren’s comments were the first confirming Haden’s suspension, which was first reported last month. Haden reportedly failed a test for taking Adderall, which is on the league’s banned substance list.
