Knicks interim coach Kurt Rambis said there’s still a chance guard Jimmer Fredette signs a second 10-day contract, but admits management is “collecting names’’ off the waiver wire, looking at younger players to develop.

One player who could fit that bill is San Antonio third-string point guard Ray McCallum, a 2013 second-round pick who is being waived to make room for veteran Andre Miller.

Fredette’s 10-day contract expires Thursday, so his last game could be Tuesday against Portland at the Garden. He’s appeared just once — last Monday for a 1:49 stretch of garbage time. Fredette has been a DNP the last three contests, with Rambis saying last week he’s gotten “pushed around a little’’ on defense during scrimmages.

The Garden fans chanted “Jimmer’’ during Sunday’s loss to the Heat, but that didn’t move Rambis to play him. Rambis lightened his tone on the popular guard from upstate Glens Falls but admitted Fredette will be hard-pressed to make the rotation even if re-signed to a second 10-day deal.

Rambis alluded to potentially signing a younger player recently waived with an eye on next season, too.

“Yes, yes, yes,’’ Rambis said. “Management is collecting [names], that’s what they’re doing. [They’re] talking about guys, thinking about guys, not only for this season [but] bringing guys in they might want to hold onto and bring them to summer league next year and work out during the summer. There are a lot of names floating around out there.’’

The Knicks have needed point-guard help all season, and McCallum has been immersed in a championship system, playing 31 games this season for the Spurs after spending his first two seasons with Sacramento as a teammate of Derrick Williams.

Rambis, upon Fredette joining the club, said he didn’t consider the former BYU superstar as a point guard in the NBA, feeling he was more a 2 guard.

Rambis has been tough on Fredette since his arrival, but lavished him with praise Tuesday.

“He’s a great competitor, a feisty guy and I like that,’’ Rambis said. “He’s not afraid to compete, not afraid to go against anybody. He’s got great passion and spirit for the game. I really like the way he approaches it. There’s tremendous enthusiasm when he’s out there on the court. All those things bode well for him.”

Asked if he’d want Fredette on a second 10-day, Rambis said: “Sure I would. That’s a management decision on what they’re going to do. We got a roster spot. We got Cle [Cleanthony Early], who could be coming back soon. It’s going to be very difficult for [Fredette] to break in the rotation.’’

Rambis was asked about their interest in veteran Joe Johnson, who signed with Miami, and admitted he wasn’t on the radar because of the playoff situation.

“He’s looking to get into the playoffs,’’ Rambis said. “Some guys know you’d feel is a possibility and some guys aren’t, looking in another direction.’’

Early (gunshot wound) could scrimmage as soon as next Monday, but it might be with the Westchester Knicks. Rambis said the Knicks considered bringing Early on their West Coast trip to participate in Monday’s practice in Denver, but they are leaning instead toward keeping him here to work with the D-League team in a rehab situation.

While celebrating his girlfriend’s birthday, Early was shot in the knee after getting robbed outside a Queens strip club on Dec. 30.

Arron Afflalo had an MRI exam on his knee, and it came back negative. He is questionable for Tuesday night.

Rambis said his communication with Phil Jackson has been terrific and they speak every day. Jackson had a film session with the coaches last week. That was an issue with Derek Fisher when some coaches failed to show up for a film session Jackson had called. But Rambis indicated Jackson still is miserable with the losing. “Nobody’s happy about it,” he said. “We’re all frustrated. Nobody in this organization is OK with where we’re at. We’re looking at personnel decisions. We’re looking forward to free agency. There’s a lot of basketball talk, and communication is going on. But nobody is happy with where we’re at. We have to be better in a lot of areas.’’
