The Rangers recently agreed to contract terms with K'Andre Miller, the team's first-round pick in the 2018 NHL Draft.
On Friday, the Rangers hosted a Zoom video call with the 20-year-old to help introduce him to the fans. During the call, someone in the video chat repeatedly posted a racial slur, flooding the chat and not allowing any other questions to come through.
Eventually, the NHL team was able to disable the chat entirely.
"The National Hockey League is appalled that a video call arranged today by the New York Rangers to introduce their fans to one of the league's incoming stars, K'Andre Miller, was hacked with racist, cowardly taunts.The person who committed this despicable act is in no way an NHL fan and is not welcome in the hockey community," the NHL said in a statement.
"No one deserves to be subjected to such ugly treatment and it will not be tolerated in our league. We join with the Rangers in condemning this disgusting behavior."
Meanwhile, the Rangers released a statement of their own, saying: "We held an online video chat with fans and New York Rangers prospect, K'Andre Miller, during which a vile individual hijacked the chat to post racial slurs, which we disabled as soon as possible. We were incredibly appalled by this behavior, which has no place online, on the ice, or anywhere, and we are investigating the matter."
