WWE Clash of Champions took place on Sunday night. 

September's PPV was billed as a big one, considering it's the one night of the year when every title must be defended.

There were a number of monster matches booked, too. 

Roman Reigns vs Jey Uso was undoubtedly the biggest feud heading into Sunday night and all eyes were on the family affair as it closed the show. 

But there were plenty of other matches that impressed over the course of the evening. 

Drew McIntyre put his WWE Championship on the line against Randy Orton in an Ambulance Match, while Zelina Vega finally got a shot at the RAW Women's title. 

So, let's get down to business. You can check out the full results from Clash of Champions below.
