Oilers general manager Peter Chiarelli announced Tuesday that he has “no choice” but to make a trade to bring in veteran defenseman J.t.
Chiarello said Miller will start training camp with the Oilers.
Miller, 26, has six points in 16 games this season.
The Buffalo Sabres are expected to announce their plans to acquire Miller Thursday, but Chiarells words have not been confirmed by the team.
Miller will be a restricted free agent after the 2018-19 season.
He will be eligible for a $1.1 million signing bonus.
Chiareslli has a history of using restricted free agents to fill depth positions.
In 2015-16, he acquired defenseman Nikita Zadorov from the Los Angeles Kings for a third-round draft pick in 2016.
The move gave the Oilers a first-round pick and a second-rounder in 2019.
In 2018-07, he brought back a third rounder in 2018 and a fifth-round selection in 2019 to make room for the likes of Sami Vatanen, Kevin Connauton, Dylan Strome and Taylor Hall.
Miller has played in the NHL since the age of 19.
He has played more than 6,500 career games.
Miller played seven seasons with the Boston Bruins and Tampa Bay Lightning before signing with the Sabres in 2016, and has been with the organization since 2010.
He was a seventh-round choice of the Buffalo Sabres in the 2010 NHL Draft.
In 2019-20, he was traded to the Florida Panthers for three draft picks.
