Conor McGregor was on hand for the Bellator Dublin event to support Sinead Kavanagh in her fight against Arlene Blencowe. After the Blencowe-Kavanagh match, McGregor spoke in the postfight interview and detailed his injury status along with his plans to return to the Octagon later in the year.

Saturday's reinvigorated main event is a rematch of the fiery fight last November in which Alex Pereira won the belt. It was tightly contested and swung in both directions -- mostly toward Jiri Procházka, honestly -- before Pereira landed a left hook counterpunch in Round 2 that was the beginning of the end. Speaking of beginnings, though: The most spine-tingling highlight came during prefight introductions, when the fighters stood in their corners staring across the cage at each other, neither man moving a muscle. If Pereira and Procházka can bring that chilling energy again Saturday, we're in for a good one.

Several storylines will play out at UFC 303. Here are the most intriguing, framed as questions to be answered on fight night.
