Camera + Lens Rental/Borrow

Hey, I've been asked to take photos for a fight event, and it would be my first event of this kind. However my current gear is most likely not suited for the lighting that will be at the event ( using a Canon 200D and have a kit lens, telephoto (50-250mm 4-5.6) and 50mm prime) and I should have access to my friends full frame but that is limited to the same 50mm prime.

Given the kind of shots that would be required, looking to see if I can rent a 24-70 f2.8 or something close for the 4 days ( Dec 4 - 8 )

Appreciate any and all help!
