Hanley was placed on waivers Monday, Stars radio analyst Bruce LeVine reports.
Hanley has been a healthy scratch for half of Dallas' 16 games since Jan. 25, so this move doesn't come as a surprise. Look for the 32-year-old defender, who's picked up just three assists through 32 top-level appearances this year, to head to AHL Texas if he passes through waivers unclaimed.
