Liles looked like the odd man out on the blue-line during the pre-season, something that became even more clear after Cody Franson signed. If he's not claimed by another NHL team, Liles could be assigned to the AHL's Toronto Marlies.
The 32-year-old has a US$3.875-million salary-cap hit. If he's sent to the minors, $925,000 of that would come off the Leafs' cap under the new collective bargaining agreement.
In addition to Liles, the Leafs put forwards Trevor Smith and Troy Bodie, defenceman T.J. Brennan and Korbinian Holzer and goaltender Drew MacIntyre on waivers with the intention of sending them to the AHL.
Those moves make it likely that 19-year-old defenceman Morgan Rielly will be on the team to start the regular season. Rielly could play up to nine games in the NHL before Toronto burns a year of his entry-level contract.
NHL rosters must be set by 5 p.m. Monday. By then, the Leafs must be under the $64.3-million salary cap.
