Lombardi returned to Phoenix this season after being traded from Toronto during training camp. He missed 12 games early in the season with an upper-body injury and didn't provide the Coyotes with the scoring punch they had hoped.
Lombardi had four goals and four assists in 21 games with Phoenix and was a healthy scratch on March 25 against Detroit after failing to register a point in seven straight games.
McMillan played six games with the Ducks this season and had one assist. He had eight goals and five assists in 41 games with Norfolk of the AHL.
