Kevin Smith is returning to the Lions under a one-year contract. Smith posted a message on his Twitter account Tuesday after finding out he would be back in Detroit. "Just finished a great work out with frank gore, and Matt forte and just found out I will be back n the d next year. #imback," he wrote. Smith, 25, rejoined the Lions during the 2011 season after not being tendered a contract during the offseason and helped to fill the void left when concussions derailed Jahvid Best's season and rookie Mikel Leshoure tore his left Achilles tendon.
