The team moved to the Bull City after Wake County leaders turned down a deal with the university.
The university will use the 50-year-old facility for its football games. With no stadium of its own, the Bears will play for one year in Durham.
Shaw University spent $90,000 cleaning up and painting the stadium.
Durham County Manager Mike Ruffin said the university and the county are working on a 10-year deal that would bring nearly $5 million worth of upgrades such as new field turf and an eight-lane track to the stadium.
