SAN ANTONIO — Warriors center Zaza Pachulia is questionable for Game 4 with a right heel contusion. Pachulia didn't return after leaving Game 2 on Tuesday in the first quarter. He finished the game with four points, two assists and a rebound in seven minutes, and he had an MRI on Wednesday that came back clean. Still, Pachulia missed Game 3 on Saturday. JaVale McGee started at center and had 16 points in 13 minutes. Connor Letourneau is a San Francisco Chronicle staff writer. Email: cletourneau@sfchronicle.com. Twitter: @Con_Chron
