Jack’s play may spell end for Sessions

In the second quarter Wednesday at Amway Center, Jeff Hornacek motioned to the bench. Point guard Ramon Sessions popped up, started taking off his warm-up top. It was a false alarm. A Knicks assistant told him to sit back down.

Either Sessions misread Hornacek’s intentions or, as the veteran said, “Coach changed his mind.”

It became another game in which Sessions did not play, and his future as a Knick is unclear. After starting the season’s first three games, when the Knicks began 0-3, he has been pinned to his seat — only playing during garbage time of a blowout loss to the Rockets.

Sessions has always been in a rotation in his 11 seasons, saying this is “a little adjustment.’’

“I’ve played my whole career, first time in my 11 years this has actually happened,” Sessions said in his first remarks on his demotion. “I’ve been around a while, been around different scenarios. It’s still early. It’s a long season. In the NBA, a lot of things can happen.’’

Jarrett Jack was elevated to starting point guard, and the Knicks are 6-2 since. Jack has made a point of focusing on setting up Kristaps Porzingis. It’s no coincidence Jack had his worst game Wednesday in Orlando (six turnovers) without Porzingis, as the club suffered a 112-99 loss.

Previously, Jack had been credited with organizing and calming the offense amid allegations the players didn’t know all the plays. It was implied Sessions, a penetrator, wasn’t working out in that area. Sessions doesn’t buy it. “I don’t think it’s something I fell short of,’’ he said. “The more practices we got, the more games we played, it would get to that point. It wasn’t nothing I was lacking in that department.”

The Knicks need to open a roster spot Sunday to make room for Joakim Noah’s return from a drug suspension. Sessions hasn’t heard from Knicks management. General manager Scott Perry, in praising his professionalism Wednesday, declined to say whether the free-agent signee would be on the roster by Monday.
