The St. Louis Blues are evaluating the market for struggling defenseman Vince Dunn.

"I'm told that the Blues have engaged with teams (in) conversations about Vince Dunn," TSN's Frank Seravalli reported Tuesday on "Insider Trading."

The Blues made Dunn a healthy scratch Tuesday night against the Vegas Golden Knights, according to Jim Thomas of the St. Louis Post-Dispatch. The rearguard has collected one goal and one assist while averaging 16:32 in ice time over the first six games.
