The Pistons haven't officially been sold to private equity financier Tom Gores because the two sides can't agree on a price.

The NBA believes the team should be sold for $420 million, but the Ilitch family only offered $360 million for the franchise.

Sources tell The Detroit News that both sides are closing the gap, but Gores' exclusive negotiation period will likely be extended another two weeks.

NBA commissioner David Stern said Saturday during All-Star Weekend in Los Angeles that a resolution is expected this week and that all signs are positive.

"We know that there are very intense negotiations going on, which are in their final stages," Stern said. "Either there will be a deal or there won't be a deal within the next week. And every indication is there will be a deal, and we'll see how that goes."
