Running Back/Kick Returner Kory Sheets suffered a season-ending injury to his right Achilles tendon on Wednesday, and the Dolphins subsequently waived him, according to Barry Buetel, Miami Dolphins Director of Broadcast Services. Sheets was a primary candidate for return duties, but his season ends along with AJ Edds's. There's no guarantee he'll be brought back in 2011 considering the running back depth in South Beach.
