Zimmer's wish was granted by Make-A-Wish Illinois, and with help from the Blackhawks, he and his family were given a tour of the arena, Blackhawks locker room and training room before their game against the Pittsburgh Penguins.
"Today I woke up and got picked up in a limousine, then we got to drive around the United Center," Zimmer said in a video posted on the Blackhawks website. "Then … I got dressed and we went to practice with the Blackhawks."
During his practice, Zimmer chatted with Blackhawks goalies Corey Crawford and Scott Darling, stopped shots from the other players and posed for a picture with the team after practice.
