Zubrus cleared waivers at noon on Thursday.
"I feel I can definitely play and I'll be approaching the rest of the summer like I'm going to be playing," Zubrus said. "I don't know how long I'll have to wait to find a spot that I think works for me and the team, but I'm getting ready to play hockey. That doesn't change."
Zubrus, 37, had been a member of the Devils since the 2007-08 season. Last year he appeared in 74 games and scored four goals and recorded six assists.
