With a chance to win a starting offensive 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 team's voluntary workouts, the Detroit Free Press reported.
The fourth-round pick in 2010 spent last season as the Lions' No. 4 offensive 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.
If Fox can stay healthy and prove to be a solid right tackle, it would allow the Lions some versatility along their offensive line. The thought process on the Lions appears to be: draft a left tackle with the No. 5 pick in the upcoming 2013 NFL Draft, have Fox win the right tackle spot and move Reiff inside.
That plan would make the Lions a much better run-blocking team -- an area in which they struggled mightily last season. However, with Fox's injury concerns and relying on a rookie left tackle (who might be off the board at the fifth spot), the Lions might be gambling with Matthew Stafford's protection.
