HOUSTON — The Knicks still need to fill out their roster to meet the NBA requirements and are making two expected moves. 

With Tuesday’s deadline upcoming to reach the minimum of 14 NBA standard contracts, the Knicks plan to sign wing Matt Ryan and convert the two-way contract of center Ariel Hukporti, a source confirmed Monday. 

Ryan, a local product from Iona Prep, is a 27-year-old sharpshooter who has already played for four NBA teams. He agreed to sign with the Knicks but a source said Monday the structure of the contract is still being worked out — specifically whether it’ll be a standard or a two-way deal. 

If it’s a two-way contract, the Knicks would still need to sign another player to get to 14 by Tuesday. They’ve maintained interest in Landry Shamet, who was on a path to the final roster before dislocating his shoulder in preseason and getting waived. 

The Knicks used their top two picks in the G-League draft last month to nab the rights to Ryan and Shamet. Drafting Shamet also allows the Knicks to oversee his recovery and progress.

Shamet, thus far, has avoided surgery, opening up the possibility of him returning early in the regular season. 

“Obviously, Landry is going through the rehab process,” coach Tom Thibodeau said recently. “We’re excited about Matt just because of the skill set, the shooting. Feel like you can’t have enough shooting, but we like both guys a lot.” 

The Knicks will have that open two-way spot after signing Hukporti, the 58th overall pick from this year’s NBA draft. He has logged 29 minutes this season — mostly in garbage time — as the third center behind Karl-Anthony Towns and Jericho Sims.

He’s also fully recovered from a meniscus injury prior to the draft and is moving with more speed than during a clunky summer league. 

“Everything is possible,” Hukporti said in his only interview as a Knick during preseason. “It doesn’t matter where you get drafted or where you’re from or whatever. Personally, I’ve been to America a couple times before, when I was 14, 15, working in the summer in [Los Angeles], and all that. So it was definitely a new experience as well because I never played a real game in America. And it was like, ‘OK, everything is way faster, not that many plays, it’s just like give and go,’ so it was definitely hard for me to adjust to at first. But now I got used to it.” 

Hukporti is probably the closest on the active roster to a prototypical rim-protecting Thibodeau center, at least until — or unless — Mitchell Robinson returns from his ankle problems.

There could be an opportunity for Hukporti to play since New York’s frontcourt rotation is prone to volatility. 

Neither Robinson nor Precious Achiuwa has played yet this season, although the latter is expected to return shortly from his strained hamstring. During a defeat to the Cavaliers on Oct. 28, Thibodeau used Hukporti as his backup center in the second half instead of Sims. 

Sims rebounded with his best performance in Friday’s blowout over the Pistons, prompting Thibodeau to label the center’s progress as “very good.” 

With Ryan, a 6-foot-6 native of New Rochelle, the allure is shooting. He knocked down 45 percent of his treys last season with the Pelicans.

The Knicks don’t have an established first small forward off the bench, using the rookie Pacome Dadiet in the opener before pulling the plug. 

“Matt’s a high-level shooter, can make shots on the move, off the catch. Super confident dude,” said Ty Jerome, the Cavs guard who was teammates with Ryan at Iona Prep and New Heights AAU, told The Post. “Not scared of anything, man. So I think if he gets the opportunity, he’ll fit New York well.”
