Allis has been battling for a roster spot with the Minnesota Wild, but the team has released the defenseman and will have to make a roster move.
Allis is scheduled to practice Thursday at the Minnesota-Duluth MHS facility.
This marks the first time Allis will have been on a line with Erik Haula and Kevin Fiala.
He was expected to get the start against the Wild on Wednesday, but it looks like the line could be shifted to an opening night lineup with a different goaltender.
The Wild, however, are set to open up the season on a home-and-home with Chicago.
