St. Louis Blues defenseman Vince Dunn will not play Monday night in Game 1 of the Stanley Cup Final because of an upper-body injury.

Blues coach Craig Berube also announced that rookie forward Robert Thomas, who is dealing with an undisclosed injury, will play Monday night against the Bruins.

This will be Dunn's fourth straight game missed with the injury after he took a puck to the face in Game 3 of the Western Conference final.

Berube said Dunn is still considered day-to-day but that he is close to a return. Dunn practiced Monday for the third consecutive day and shed the full face shield he skated with over the weekend in favor of a regular visor.

Asked if Dunn was talking better, captain Alex Pietrangelo joked, "Yeah, his teeth are coming in.''

Dunn had 12 goals and 23 assists this season with a plus/minus of 14. He has two goals and five assists this postseason with a plus/minus of minus-3.

Thomas, 19, had nine goals and 24 assists during the regular season and has a goal and five assists in the postseason.
