Ali vs. Frazier. Mayweather vs. Pacquiao. Balboa vs. Creed. Next on that list of famous fights? An Uber driver vs. a Lyft driver — and it’s going down in Philly.

For some reason, Uber driver George Robertson Storm will fight Lyft driver Danny Mac “to settle their dispute” in a three-round battle in the boxing ring. The details are scant; we don’t know when or where this fight is going down.

But Philadelphia personal injury attorney Jason Fine and Celebrity Boxing Promoter Damon Feldman announced a press conference will take place Thursday to reveal details about when, where and — crucially — why. Apparently both drivers “will do a staredown” and talk about the fight.

We’ve put in a call to Fine’s office and will update when we have some more details.

Across the country, ridesharing giants Uber and Lyft are staunch competitors. Uber’s known for its ubiquity and being the clear winner in every metric from cash raised to drivers employed to rides taken. Lyft is smaller, but often has a reputation of treating its drivers, well, better and providing a more personable experience for riders.

UberX launched in Philadelphia in 2014 and Lyft, which was at that point still rocking pink mustaches on the front of its cars, came to Philly shortly after in January 2015.
