UFC 307, held Saturday at the Delta Center in Salt Lake City, Utah, delivered an electric night of fights with excellent finishes, upsets, and title shake-ups. 

Conor McGregor's return to the octagon has been delayed, causing a significant shake-up in the UFC 303 lineup and impacting ticket prices on the resale market. The former UFC featherweight and lightweight champion was set to fight Michael Chandler but withdrew due to an injury.
