OLB Vince Redd, who has been suspended four games by the NFL, flunked a drug test as a result of taking Sudafed, his agent, Joe Linta, told Scout.com.

"If you check the ingredients of Sudafed, it has Ephedra in it," Linta explained. "Vince said he took Sudafed around the time of a league administered test, so it was an honest mistake. I don't think he realized what was in Sudafed, which really is a cold medicine. He looks forward to continuing his career this season."

Ephedra, which is generally taken for weight loss, is a banned supplement by the NFL.

Redd was waived by the Kansas City Chiefs on Monday and passed through waivers unclaimed thus making him available to sign with any team. Redd best fits in a 3-4 defensive system.
