Per a team source

We could see defenseman Philippe Boucher return to the lineup on Wednesday. The coaching will evaluate his performance on Tuesday but there is a strong desire get in him the lineup as some in the organization see him benefiting from the Penguins new uptempo-system.
I will update after tomorrow’s practice to see how the rotation goes. If the staff decides to go with Boucher, Rob Scuderi or Hal Gill will be scratched.
