Mitchell Miller

When asked Saturday about the Bruins' signing of Miller to an entry-level contract, NHL commissioner Gary Bettman said "What he did as a 14-year-old is reprehensible, unacceptable. Before the Bruins made the decision to sign him, we were not consulted...He's not coming into the NHL. He's not eligible, at this point, to come into the NHL. I can't tell you that he'll ever be eligible to come into the NHL. If, in fact, at some point, they think they want him to play in the NHL -- and I'm not sure that they're anywhere close to that point -- we're gonna have to clear him and his eligibility and it'll be based on all the information we get firsthand at the time. So the answer is, they were free to sign him to play somewhere else, that's another league's issue. But nobody should think, at this point, he is or may ever be NHL-eligible."

Miller signed a three-year, entry-level contract with Boston on Friday.

Miller has been dismissed from the University of North Dakota hockey team, the school announced Friday.

Arizona renounced the player rights for Miller on Thursday after previously selecting him in the fourth round of the 2020 NHL Draft.

Miller was drafted 111th overall by the Coyotes at the 2020 NHL Entry Draft on Wednesday.
