LaVine will get an MRI on Saturday, but there's initial confidence that he hasn't suffered a serious injury, sources told ESPN's Adrian Wojnarowski.
LaVine appeared to begin laboring after grabbing an offensive rebound with just under nine minutes remaining in the first quarter. On the next play, he took an intentional foul on Warriors guard Stephen Curry before taking himself out of the game.
He immediately walked toward the Bulls' locker room with a team trainer, but LaVine was able to move under his own power.
LaVine is averaging 25.6 points on 49% shooting (41% from 3), 4.6 rebounds and 4.3 assists in 37 games for the Bulls this season.
