Pirri, a 2009 second-round pick by the Blackhawks, suffered an undisclosed injury during training camp and was among coach Joel Quenneville’s final roster cuts last month. Pirri has three assists in three games with the IceHogs this season.
Pirri told ESPNChicago.com earlier in the week he was still working toward an NHL opportunity.
“You can’t control where you are,” Pirri said in Rockford on Wednesday. “You just have to do the best with the situation you have. Obviously getting into some games and getting back into a routine, that helps a lot. I just want to show well. Hopefully, I get that opportunity with the Blackhawks or somewhere else.”
Hayes played in two of the Blackhawks’ first four games. He had zero points and a plus-1 rating. He was a healthy scratch against the New York Islanders on Friday.
