The Detroit Lions started their official offseason workout program today (Monday). It included defensive end Willie Young and tackle Jason Fox.

Young signed a one-year deal instead of his restricted free agent tender, according to the Lions’ web site.

Fox signed a one-year restricted free agent tender worth $1.323 million, per the team. He is expected to compete for one of the open tackle positions along with Riley Reiff and Corey Hilliard.

 The Lions also brought back wide receiver Brian Robiskie with a one-year deal after he had been released last week.

 They have also signed their exclusive rights free agents — running back Joique Bell, fullback/tight end Shaun Chapas, safety Ricardo Silva and wide receiver Kris Durham.  All four saw at least some game action last season and were expected to  sign.

 The offseason program, defined in the NFL’s collective bargaining agreement, starts slowly. Strength and conditioning work, along with physical rehabilitation, are allowed during the first two weeks.
