Otto Porter Jr. will not play in the game because of a foot injury.
Porter was not expected to play on Thursday, according to Chris Haynes of Yahoo Sports.
The Warriors said midway through Game 3 that the 28-year-old was battling left foot soreness after being limited to 6:49 on the court. X-rays on his foot were negative.
Game 5 is on Thursday at 9 p.m. Porter was listed as questionable.
The veteran has been a dependable player for the Warriors. In the regular season, he shot 38.0 percent from three-point range. His numbers have gone down slightly in the playoffs, but that is expected since head coach Steve Kerr is leaning on his starters a little more.
Kerr has to move Jonathan Kuminga up the rotation because of Porter's injury.
In Game 4, Kuminga spent 21:39 on the court. He had 17 points and eight boards.

The finals are scheduled to start on June 2. Golden State closing out the conference finals in Game 5 would allow Porter to have a little extra time off to heal his foot.
