Johns suffered a concussion in Tuesday's game against the Avalanche, Mike Heika of The Dallas Morning News reports.

EDGE Analysis

The Stars play next in Edmonton on Thursday, but it's unlikely Johns will be able to play that game, and with the Canadian road trip on the agenda, it wouldn't be surprising if he was sent home to Dallas to recover. Either Jamie Oleksiak or Greg Pateryn will fill in for the time being.

Johns left Tuesday's game against the Avalanche with an upper-body injury and won't return.

EDGE Analysis

Johns has proven to be a well-rounded player this season with three points, 16 shots on goal, 18 hits and 18 blocked shots through eight games. The severity of this injury is unclear, and his next opportunity to play will be Thursday in Edmonton.

Johns finished Saturday's win over the Avs with an assist and a team-leading six hits.

EDGE Analysis

It was a solid game for Johns. He also contributed three shots and three blocked shots. This is basically the best case scenario for anyone rostering Johns. His ceiling isn't high, but he's capable of contributing decent numbers across categories.

The Stars have elected to protect the 6-foot-4 Johns against expansion.

EDGE Analysis

Johns would have been an alluring player for Las Vegas if he hadn't been protected. It's an indication that the team believes he's going to play a big role for the young blue line in the coming season.

Johns led the Stars with nine hits and three blocked shots in Sunday's loss to the Bruins.

EDGE Analysis

Johns has gone 17 games without a point, but he can add some value in categories like hits and blocked shots. The only drawback is that it's hard to know if he'll be in the lineup on any given night until the day of the game.

Johns will be on the ice for Sunday's game against the Bruins, reports NHL.com's Mark Stepneski.

EDGE Analysis

Following an illness, Johns has drawn into the lineup in two straight games. On a team with eight defensemen, that's a sign of coach Lindy Ruff's trust in the 24-year-old. However, he's been locked into the third-pairing logging limited minutes and not producing much fantasy value. He hasn't put up a point in 16 games and has a minus-7 rating over that span.

Johns (illness) is a lineup option, per coach Lindy Ruff, meaning he is healthy enough to play for Friday's game against the Coyotes.

EDGE Analysis

Just because Johns is healthy again doesn't necessarily mean he will draw into the lineup, and in fact, he is projected to be a healthy scratch for Friday's contest. Considering his paltry eight points in 44 games this season, he shouldn't be rostered in the majority of fantasy formats anyway.

Johns (illness) won't be fit to return for Saturday's home game against the Lightning.

EDGE Analysis

Johns is a stay-at-home type of defenseman who has laid into opponents 117 times with 90 blocked shots in only 44 games this season. He'll give way to Jamie Oleksiak in this upcoming contest, the last one before the Stars get to enjoy a five-day bye.

Johns (illness) isn't expected to play Thursday against Minnesota, Mike Heika of the Dallas Morning News reports.

EDGE Analysis

With Johns likely unavailable Thursday, Patrick Nemeth is expected to slot into the lineup against the Wild. Johns has been a decent bottom-pairing defender for the Stars this season, but his meager offensive production -- eight points in 44 games -- keeps him off the fantasy radar in most formats.

Johns was scoreless in Tuesday's 6-3 win against the Maple Leafs, but he was able to post a game-high six hits.

EDGE Analysis

Johns is up to 100 hits through 37 games. His hits and blocked shots (71) are his biggest contributions to fantasy owners in deeper pools, as he is scoreless in eight straight games, and 11 of the past 13 outings.
