It's been a strange NFL journey for former Brigham Young running back Harvey Unga since he was drafted in the seventh round of the 2010 Supplemental Draft.
Unga, who has left the Bears twice for personal reasons, was reinstated to the active roster, and he's able to participate in the offseason program now.
What his role, however, is unclear, since the Bears have a new general manager, and they have much more depth at the position.
The Bears have signed Michael Bush, and they appeared to have found a quality fullback in Tyler Clutts.
Unga showed some flashes during the preseason last year. But, he was placed on the reserve/ left squad list last September.
The Bears kicked off their voluntary workouts at Halas Hall today, and the only significant no-show was Pro Bowl running back Matt Forte. The team placed a franchise tag on him, but Forte is seeking a long-term contract.
