The Dallas Stars will likely be without defenceman Stephen Johns for all of the 2020-21 season. That's according to a report by The Athletic's Saad Yousuf.

The 28-year-old is entering the last year of his three-year, $7.1-million deal signed in 2018. He was named as one of the three finalists for the Masterton Trophy this past season alongside Bobby Ryan and Oskar Lindblom.

Johns missed the 2018-19 campaign and the first 47 games last season due to post-traumatic headaches stemming from a concussion suffered in March 2018. He appeared in four round robin games during the Stars' run to the 2020 Stanley Cup Final, but left in Game 1 of the first playoff round and didn't return during the postseason.

The Stars have released their training camp roster and Johns is listed as injured and not participating. His $2.35 million cap hit will likely be moved to long-term injured reserve once training camp ends.
