With a chance to win a starting tackle job, Jason Fox wasn't about to miss the Detroit Lions' offseason workouts. Fox, a restricted free agent, will sign his one-year tender Monday and take part in the voluntary workouts, the Detroit Free Press reported. The fourth-round pick in 2010 spent last season as the Lions' No. 4 tackle, but with the departure of Gosder Cherilus via free agency and Jeff Backus to retirement, the injury-plagued Fox has a chance to win one of the starting tackle jobs. The Lions' 2012 first-round pick, Riley Reiff, also will battle for a starting job at either tackle spot or at right guard. If Fox can stay healthy and prove to be a solid right tackle, it would allow the Lions some versatility along their offensive line. Source: NFL.com
