Needing help at running back, the Lions have signed DeDe Dorsey according to ProFootballTalk.com. Dorsey, who has not played a regular season NFL game since 2008, was the most valuable player in the United Football League’s championship game while playing for the Las Vegas Locomotives in November. After playing in college at Lindenwood, an NAIA school in Missouri, the 25-year-old running back was signed by the Bengals in 2006. After they cut him he played with the Colts as a rookie. He returned to Cincinnati and played there is 2007 and 2008. With top running back Kevin Smith coming back from ACL surgery (and shoulder surgery), the Lions are filling a need. It is uncertain if Smith will be a full-go when training camp starts.
