Delia signed with the Blackhawks in July of 2017, and played with all 3 Chicago affiliates - Blackhawks, Rockford IceHogs and Indy Fuel. He made his NHL debut on March 29, 2018, which just so happens to be the day Scott Foster made his EBUG debut due to injuries suffered by Crawford, Forsberg, and Delia.
Delia returned to the IceHogs at the start of the 2018-19 season, but was recalled again to back-up the Blackhawks for the injured Crawford. He went back and forth a couple more times, and after 5 seasons, was picked up by the Canucks in a one-year $750,000 deal.
