Gregg Popovich will not coach the Spurs in Game 4 against the Spurs.
Popovich also missed Game 3 following the passing of his wife, Erin Popovich.
Ettore Messina will fill in for Popovich as he did Game 3.
"I think, of course, that it's a tough situation," Messina said Saturday. "But the first thing is to free our minds and realize that if you watch the [video] of the last game, we had more points in the paint. We had more free throws. We won the boards.
"Against a fantastic team like they are, we know what we're playing against. Doing everything a little bit better will be, of course, the key. I think the team is ready to play and compete. You can't get frustrated. You've got to get back on the court and try to prove everybody wrong."
