Moore, who is recovering from a fractured neck, a concussion and other injuries, walked out of the hospital, KUSA-TV reported.
The rookie player was injured March 8 in a blind-side attack by Todd Bertuzzi of the Vancouver Canucks. Bertuzzi was suspended for the rest of this season, and possibly longer, by the NHL.
An Avalanche statement prior to Moore's release from the hospital, said:
"His neck fractures are expected to heal over the next 6-12 weeks with stabilization using a cervical brace. However, his overall recovery and prognosis is uncertain, including his ability to return to professional hockey."
Dr. Andrew Parker, the team physician, said when Moore recovers from the neck injuries and concussion he will begin physical therapy and rehabilitation.
"Steve is hoping to address the media sometime in the future but wishes to convey now his sincere thanks and appreciation to everyone who has expressed their concern for his well-being, and to the Avalanche organization and doctors for their tremendous care and support," said Larry Kelly, Moore's agent.
