Thomas (undisclosed) isn't expected to be in the lineup for Thursday's Game 5 against the Bruins, NHL.com's Louie Korac reports.

EDGE Analysis

Thomas will miss a fourth straight game Thursday and still hasn't returned to practice, so his chances of rejoining the lineup before the series comes to a close are quickly dwindling. Zachary Sanford will continue to occupy a spot on the Blues' second line while Thomas is on the shelf.
