Dvorak left Monday's game against the Wild and did not return after failing a concussion test, Arpon Basu of The Athletic reports.

EDGE Analysis

Dvorak left early in the first period, getting just 36 seconds of ice time in Monday's loss. The 25-year-old will be further evaluated over the next few days before Thursday's game against the Ducks. There's rarely a concrete timeline when it comes to head injuries, so he can be considered questionable until more information becomes available.
