Following an internal investigation, the Chicago Blackhawks said Tuesday they have placed veteran winger Corey Perry on unconditional waivers for the purposes of terminating his contract.

Perry had initially taken a leave of absence from the team. Blackhawks general manager Kyle Davidson told reporters Saturday that the decision to send Perry away from the team was made by management. Perry's agent, Pat Morris, said in a statement that same day that it was Perry's decision to leave the Blackhawks.

Edmonton Oilers goaltender Jack Campbell was placed on waivers Tuesday, making it the latest development for a preseason Stanley Cup contender that currently has the second-worst record in the NHL.

The Oilers placed Campbell on waivers for the purpose of assignment with the intent that he will play for their AHL affiliate, the Bakersfield Condors, in an attempt to gain the sort of consistency that has eluded him this season.
