Both Havlat and Zubrus spent last season with the New Jersey Devils, registering 14 and 10 points, respectively.
In August, the Blues invited forwards Scott Gomez, Spencer Asuchak, Eriah Hayes, Zach O’Brien and Evan Trupp to training camp on PTOs. Gomez ended up making the Blues roster.
According to Quant Hockey, the Blues have the fifth oldest forward group in the NHL with an average age of 28.502 years. The addition of either Havlat, 34, or Zubrus, 37, would bump that number up slightly.
The Blues are 5-2-1 this season and in the midst of a five-game home stand. They host the Tampa Bay Lightning Tuesday.
