At the conclusion of the 2016–17 season, Bereglazov signed as an undrafted free agent to his first North American contract, agreeing to a two-year, entry-level contract with the New York Rangers on April 21, 2017.[2]
After attending the Rangers training camp, Bereglazov was reassigned to begin the 2017–18 season with their American Hockey League (AHL) affiliate, the Hartford Wolf Pack. He appeared in 13 games with the Wolf Pack, posting 4 points, before he was returned on loan to his Russian club, Magnitogorsk, on November 6, 2017.[3] Bereglazov played out the season contributing with 3 assists in 25 games in Magnitogorsk.
On April 10, 2018, Bereglazov was placed on unconditional waivers by the Rangers, paving the way for a mutual termination of the final year of his contract with the Rangers.[4] He immediately returned to his native Russia, rejoining his original club, Metallurg Magnitogorsk.[citation needed]
