The Mavs were pegged back to 2-2 in the series, having led 2-0, with Kawhi Leonard's efficient double-double of 29 points (on 11-for-15 shooting) and 10 rebounds inspiring the Clippers on the road.
Paul George added 20 points as the Clippers became the first team in league history to lose the first two games of a playoff series at home and then win the next two on the road by a combined 35-plus points.
Doncic was cleared to play despite a neck strain and put up 19 points, but the Mavs star was just nine-for-24 shooting in Dallas, where he frequently showed signs of pain as he grimaced his way through proceedings.

Game 5 is Wed. at 10pm/et on TNT.
He did not want to use it as an excuse, though.
"I don't think that matters right now," Doncic said. "We lost. Injuries are part of basketball, but I was 100 per cent. I played terrible, so we've just got to move on to the next one.
"The pain is like neck and then the nerve down. I don't really know how to explain that. It felt way better today morning than yesterday.
"I'll just keep doing massages, ice it down and then be ready for Wednesday."
Mavs coach Rick Carlisle is hopeful Doncic will be free of the symptoms of his injury by Game 5.
"He's in pain," he said. "It appeared to me that he couldn't turn left, couldn't look to his left. He couldn't turn his neck to his left, and that's difficult for a guy that relies on peripheral vision and basically has played his whole life with his head on a swivel.
"We've got to hope in the next couple of days that he can get better, hopefully substantially better. There is a two-day break between games, which is a positive in this case."
