The man they call “Snacks” is ready to feast on his old teammates from the Jets’ offensive line. Damon Harrison just wishes Saturday night’s Giants-Jets clash was a regular-season game.

“I kind of hate that it’s a preseason game,” the Giants defensive tackle said on Thursday. “All games count, preseason or not, but it would be that much more fun and exciting if it was a regular-season game.”

Still, Harrison said he isn’t feeling much of a rivalry between the MetLife Stadium co-tenants.

“I wouldn’t call it a rivalry,” he said. “I think it’s more for the fans. And you know, a respect thing around the town, seeing each other out, the Giants and the Jets. But as far as Cowboys-Giants and Jets-Patriots, it’s not that kind of rivalry.”

Harrison, who signed with the Giants after spending his first four seasons with the Jets, said he still talks to his old defensive linemates on a nearly daily basis. And he’s also looking forward to going up against some of the same offensive linemen he used to battle in practice.

“I’m excited to see everybody, but the entire O-line,” he said. “It’ll be fun to have on a different jersey and go up against them. It’ll be weird at first, but hopefully [Nick] Mangold gets to play, because we’ve always had some good battles. He’s still one of the better centers in the league.”

Secondary/safeties coach Dave Merritt Sr. said he expects rookie S Darian Thompson to play in the season opener even though he will miss the Jets game with a shoulder injury. “He will be ready,” Merritt said . . . Of first-round pick Eli Apple, who will return against the Jets after suffering a knee strain in the preseason opener, Merritt said: “I truly believe that this kid is going to be one of the great ones for us down the road.”
