Lombardi was injured in the second period of Phoenix's 5-3 loss Thursday night and didn't return.
Lombardi, who came to the Coyotes in a trade with Toronto on Wednesday, sat out the entire 2010-11 season with a neck injury while playing for Nashville, though coach Dave Tippett said on Friday the injury wasn't something he's had a problem with before. Lombardi returned last season to score 18 points in 62 games with the Maple Leafs.
The Coyotes called up forward Nick Johnson from Portland of the AHL to fill his roster spot.
We want to make sure that whoever makes our team really makes our team by earning it and not putting them in situations where they get preference because of their status as a first-round pick or whatever it might be. That's not going to happen. Everybody has to earn their way on our team.
