The Rangers filled their director of player development role internally.

Tanner Glass, who had been the assistant director of player development since 2019, was promoted to the primary role after Jed Ortmeyer — who had held that position since 2017 — left to pursue other opportunities, The Post’s Mollie Walker confirmed Friday.

His promotion was reflected on the Blueshirts’ website Saturday.

Glass, like Ortmeyer, is a former Rangers player, skating in 134 games across three seasons from 2014-17, and he returned to the organization in the development role after a season with the Panthers and a campaign in France.

And now, he’ll be tasked with helping fix the Blueshirts’ struggle to turn prospects into reliable — and high-end — NHL regulars.

There have been glimmers of hope recently with Gabe Perreault and Noah Laba, but for the most part, dating back to Ortmeyer’s arrival in 2017 and certainly since Glass’ return to the Rangers two years later, draft picks and prospects have continued to underwhelm.

With the Rangers in the middle of a public retool, too, the development of the pieces set to define their next era will be critical.

The Artemi Panarin trade already brought back prospect Liam Greentree.

Any other potential deals in the offseason involving established Rangers pieces will likely include draft picks or prospects.

The promotion of Glass marked the latest change impacting the Rangers on the personnel side — before any other moves for the roster follow once free agency and the offseason officially arrive — since the beginning of April, when Kevin Maxwell, a pro scout and general manager of the Blues’ AHL affiliate, was brought back as the Blueshirts’ director of pro scouting and director of player personnel.
