Johnston (undisclosed) is "probable" for Dallas' season opener.
Johnston had been unavailable for the latter half of training camp after battling an undisclosed injury but could be ready for the Stars' season opener on Thursday against the Nashville Predators. The 21-year-old is coming off a breakthrough season, scoring 65 points (32G / 33A) in 82 games, and is expecting to be a driving force for a deep Dallas Stars offense.
