On Monday, Browns cornerback Joe Haden was suspended for four games by the NFL for violating its substance abuse policy. Haden tested positive for the banned substance Adderall during a random screening in July, which is commonly used to treat ADHD.

Haden could have applied for a therapeutic use exemption from the NFL, but he failed to do so before taking the banned stimulant. Before 2010, Haden would have had the opportunity to prove his need for Adderall after the failed drug test. Presently, the TUE has to be approved before the player can start taking the drug. The use of Adderall is a controversial point in the NFL's substance abuse policy.

ESPN is reporting that the Browns were aware Haden's chances of winning his appeal were virtually non-existent.

Dimitri Patterson will take over at left corner in Haden's absence. Sheldon Brown, the other Brows starter, suffered a minor injury over the weekend that doesn't appear to be serious.
