Knicks center Willy Hernangomez admitted to being spooked in Indiana on Monday. It was the first time he played for the Knicks without his pal Kristaps Porzingis, who didn’t make the trip. It worked out well, as Hernangomez, flourishing in garbage time, posted his first double-double this season, finishing with a team-high 14 points and 10 rebounds in the Knicks’ 115-97 loss to the Pacers. “It was the first time I was on court without KP,’’ Hernangomez said. “First time with the team without KP. He’s usually next to me. I don’t like him not being around.’’ Porzingis should be around Wednesday. He was upgraded to probable as the Knicks play host to Marc Gasol and the Grizzlies after the Latvian missed two games with an ankle sprain. It has been a week since Porzingis’ right ankle bent sideways three minutes into a victory over Miami, casting a pall over the Garden. Porzingis has missed four games this season. The Knicks now can go back to their formidable frontcourt tandem of Enes Kanter/Porzingis. With Kanter missing three games around the Thanksgiving weekend because of back spasms, the duo essentially hasn’t played together for six straight games — counting the 45 minutes Porzingis missed versus Miami. Michael Beasley was unable to fill Porzingis’ role on both ends. Meanwhile, Hernangomez was Gasol’s backup during the World Championships this summer and had such high hopes for the 2017-18 season. But it has been a rough year for the Spaniard, mostly out of the Knicks rotation. He did not play Sunday versus Orlando.
