Jon "Bones" Jones defended his UFC Light Heavyweight Championship for a record sixth time inside the Octagon.
Alexander Gustafsson, ranked No. 1, came in as a steep underdog but gave the champion all he could handle. The razor-thin fight ended with a 48-47, 48-47, 49-46 decision for the champion, but Gustafsson certainly made his presence known.
His performance made the division a lot more interesting. No. 2-ranked Glover Teixeira kicked off the month of September with a decisive victory over former Top 10 fighter Ryan Bader. The contenders are starting to mount, and Jones has plenty of challengers for his gold.
These are the UFC's top 10 light heavyweights.
