Erne was placed on waivers Tuesday to reassign him to AHL Bakersfield.
Erne became the odd man out when the Oilers decided to sign free agent Corey Perry. The 28-year-old Erne does have 378 games of NHL experience, so one of the other 31 NHL teams may decide to put in a claim. Assuming he clears, Erne will end up back with AHL Bakersfield where he previously played four games this season.
