The Lions have signed DeDe Dorsey to a contract, a league source told the Detroit News. Dorsey sent a Twitter message Tuesday that read: "I am the newest member of ... The Detroit Lions. Motown here I come! I can't wait to get out there and do my thing! Back to the Jungle ... I was a Lindenwood Lion in College and now I am a Detroit Lion in the NFL ... makes sense." Dorsey also had offers from St. Louis and Minnesota.
