CM Punk started WWE SmackDown in Chicago, taking shots at Drew McIntyre. He commented on how easy it was to make McIntyre quit on RAW this week. However, his good time in Chicago was cut short.

Drew McIntyre returned to WWE television just days after saying, "screw this company, I quit," and walking out. He was unhappy with Punk's interference in his World Heavyweight Championship match at Clash at the Castle.

WWE officials, including Adam Pearce, came out to reprimand McIntyre for the attack. The Chicago fans booed McIntyre intensely. McIntyre seemed pleased with himself, having ruined Punk's big night in his home city, just as Punk had done to McIntyre in Scotland.
