While not from a verified account, former Oakland Raiders wide receiver Sam McGuffie claimed on Twitter to have had a workout with the Packers on Sunday...

McGuffie originally enrolled in college at Michigan, where he played and started at running back for one season.
After several concussions and a coaching change, McGuffie transferred to Rice where he continued to play running back and then became a slot receiver during his senior season.
Going undrafted, McGuffie signed with Oakland where he spent the offseason and training camp but was released last week.
The Packers currently have only four running backs on their roster but could be looking at McGuffie as a potential practice squad addition.
