INDIANAPOLIS — Game 5 wasn’t perfect for the Knicks.

Their turnover problems remain an issue, something that could burn them Saturday night in a do-or-die Game 6.

In the Eastern Conference finals-extending game, the Knicks started out well, committing just one turnover in the opening quarter.

That didn’t last.

They had 14 over the final three quarters, leading to 20 Pacers points.

Karl-Anthony Towns had four and has committed 12 turnovers in the last three games.

Jalen Brunson and Josh Hart had three apiece.

“It’s not just [Towns],” coach Tom Thibodeau said. “The big thing is keeping it simple. The first open man, hit him. Oftentimes, the intent is good, but we’re trying to thread the needle and we can’t do that.”

The Knicks are averaging 15 turnovers per game, which has fueled the Pacers’ transition game.

They weren’t a high-turnover team during the regular season (13.3) or first two rounds of the playoffs (12.9), but it has hurt them in this series.

In Game 4, they committed 17 turnovers, with Hart giving it away five times.

The Knicks have been here before, trailing the Pacers 3-2 in a best-of-seven series needing to win a Game 6 on the road.

In 2013, Carmelo Anthony and Co. fell short.

But in 1994 and 1995, the Knicks won in Indianapolis to force a Game 7.

Pacers reserve forward Tony Bradley (hip flexor strain) is questionable.

Aaron Nesmith, who sprained his ankle late in Game 3, was not on the injury report.

The Knicks didn’t report any injuries.

Towns has been slowed by a left knee contusion and was listed as questionable for Game 5.
