Stanton was among the Blackhawks' final training camp roster cuts and was placed on waivers on Sunday. He was beat out by Michael Kostka for the Blackhawks' final defenseman spot.
"We had eight [defensemen] here, and we were concerned he might get picked up on waivers," Quenneville said after practice on Monday. "We liked the depth he gave us, and he played well for us. It's good for him to actually get the chance to play at this level right off the bat. We wish him well. You can always use extra defensemen in your organization, and he definitely gave us that."
The 24-year-old Stanton was originally signed by the Blackhawks as a free agent on March 12, 2010. He was a restricted free agent after the 2012-13 season and re-signed for a one-year deal in July.
Stanton has played in the AHL for the Rockford IceHogs for most of the past three seasons. He had three goals, 22 assists and a plus-16 rating in 73 regular season games with the IceHogs last season. He played in one game for the Blackhawks last season and practiced with the team throughout the playoffs.
