Josh Giddey and Chicago have held their nerve on tired legs to end a five-game losing skid and stop Denver's winning NBA run at seven.
A day after a double-overtime loss in Utah, the Bulls fended off Nikola Jokic's best, piling up 40 third-quarter points and hanging on for a 130-127 win.
It ended a five-game losing streak that coincided with Australian guard Giddey's ankle injury and took the Bulls to 7-6, after a five-game unbeaten start to the season.
