Golden State has dropped six straight and 13 of 15.
"Some would perceive these to be dark days," coach Mark Jackson said. "I believe these are times to build character and hold on to the rope even tighter."
Klay Thompson scored a team-high 17 points Wednesday and had 24 in the last meeting with Dallas. He's averaging 18.3 points while starting the last 23 games since Curry's injury, often being guarded by the opposition's top defender.
"It's great experience, being doubled, grabbed and getting beaten up," Jackson said. "The great ones ... it's a complement. I think its valuable experience for him."
Including Thompson, the Warriors started four rookies Wednesday and will be looking at a similar lineup Friday. Jackson guaranteed a playoff appearance before the season began, but the rash of injuries has contributed to Golden State's problems.
A much different-looking Warriors team beat the Mavericks 111-87 on March 10, as Thompson scored 13 points off the bench, but Golden State hasn't had much luck on the road in this series of late. Dallas has won nine of the last 10 home meetings, including postseason.
