Hey, you! Stop everything! This year's One Chicago crossover event is apparently happening much sooner than anyone expected!

Chicago Fire co-creator Derek Haas announced Wednesday on Twitter that a three-way crossover between Chicago Fire, Chicago Med and Chicago P.D. is headed our way in October! "BREAKING NEWS: our second episode of the season is going to be a three way crossover with Chicago Fire leading the way," Haas wrote. "Fire into Med into PD for one night only."

The Chicago shows premiere Wednesday, Sept. 26, meaning the crossover will air the following week, on Oct. 3. Although Chicago Med snagged the lead-in spot on NBC's fall schedule, with Fire and P.D. following, Chicago Fire will actually kick off the night. Those poor casual Chicago viewers are going to have a hard time nailing down this year's schedule.
