A person with knowledge of the situation tells The Associated Press that the Detroit Pistons are working on a five-year maximum contract offer with All-Star center Andre Drummond.
The two sides started negotiating the contract after the market opened Friday, said the person who spoke on condition of anonymity because the deal had not yet been completed.
Drummond's maximum contract would be worth around $125 million according to NBA salary cap rules.

Drummond averaged 16.2 points and an NBA-leading 14.8 rebounds for the Pistons last season, giving coach Stan Van Gundy a powerful force in the paint to slug it out in the rugged Eastern Conference.
ESPN first reported the negotiations.
