Thomas will not be in the lineup against Boston for Game 2 on Wednesday due to an undisclosed injury, Tom Timmermann of the St. Louis Post-Dispatch reports.

EDGE Analysis

Thomas hasn't been in attendance for game-day skates lately, but was still able to suit up for puck drop. Apparently, the center is no longer able to power through and will miss his first game of the postseason. While coach Craig Berube wouldn't confirm his lineup, Robby Fabbri has served as the primary stand-in for practices and figures to slot into a third-line role with Thomas on the shelf.

Thomas (undisclosed) will suit up for Monday's Game 1 despite not practicing in full on Sunday, Jim Thomas of The St. Louis Post-Dispatch reports.

EDGE Analysis

Thomas joined practice late to do some work on his own but he appears to be healthy. The rookie winger notched 33 points in the regular season but has just six points in 19 postseason contests.

Thomas posted a power-play assist in Tuesday's 5-1 win over the Sharks in Game 6 of the Western Conference finals.

EDGE Analysis

Thomas had been held without a point in the first five games of the series. The emergence of the Blues' fourth line as a depth-scoring threat has led to Thomas' ice time dropping from 15:32 in Game 1 to just 9:20 in Game 6. The rookie forward has a goal and five helpers in 19 postseason games.

Thomas picked up two assists during Tuesday's 2-1 double-overtime win over the Stars in Game 7 of their Western Conference semifinals.

EDGE Analysis

The teenage rookie made his presence felt in the biggest game of his career so far, and he very nearly scored the winner himself -- Thomas' shot in the second OT rang off the post and caromed off Ben Bishop's back before falling into the crease and getting tapped home by Pat Maroon. Thomas has one goal and five points through 13 playoff games, but four of them have come in the last five contests, giving him plenty of momentum heading into the conference finals.

Thomas scored a goal on four shots and added two hits in Wednesday's 4-2 loss to the Stars in Game 4.

EDGE Analysis

Thomas has points in consecutive games after recording an assist in Game 3, as the 19-year-old rookie is finding his way in the postseason. He had 33 points in 70 games in the regular season. It's unlikely he produces consistently, but Thomas should be good for some depth scoring.

Thomas registered an assist and two PIM in Friday's 4-3 win over the Jets in Game 2 of their first-round series.

EDGE Analysis

The rookie needed just two contests to earn a postseason point, consistent with the 0.47 points-per-game pace he produced in the regular season. Thomas is skating on the third line, so his chances to produce offense will be limited, but with the next two games in St. Louis, he may find himself in more favorable situations as coach Craig Berube takes advantage of the last change.

Thomas scored a goal and added an assist in a 3-2 overtime win over New Jersey on Saturday.

EDGE Analysis

The teenager has 32 points (nine goals, 23 assists) in 66 games -- that's a 40-point pace. That's more than solid for a 19-year-old pivot in the NHL. Thomas has a strong fantasy future.

Thomas scored a power-play goal in Saturday's 4-3 win over the Lightning.

EDGE Analysis

Thomas logged 9:15 TOI, which is his lowest mark in the last 20 games, but he made the limited action count. Midway through the first period, the 19-year-old picked up the second rebound off Tyler Bozak's shot and knocked it home to open the scoring. He's been flaunting his potential lately with 10 points in 12 games during the month of March, and the Blues hope he can carry this success into a likely playoff birth.

Thomas notched two assists, one on the power play, in Saturday's 5-1 win over the Penguins.

EDGE Analysis

The teenage rookie has now picked up two goals and seven points over the last eight games, putting him firmly on the fantasy radar for GMs looking for late-season reinforcements. Thomas isn't yet a consistent performer -- he's got three multi-point efforts and four goose eggs over that stretch -- but as long as he keeps seeing time with the man advantage, his overall production could be solid.

Thomas registered an assist in Thursday's win over the Kings.

EDGE Analysis

Late in the second period, Thomas fired a shot on goal and Jonathan Quick was unable to control the rebound. It went right to Tyler Bozak, who sent it home to give the Blues a 2-0 lead. It's quite impressive that Thomas has 25 points in 55 games, especially considering the 19-year-old has spent a majority of the season on the fourth line. The coaching staff have noticed, too, as Thomas has worked on the second line with power-play minutes lately.
