Cole Miller (21-8 MMA, 10-6 UFC) has been forced out of a planned matchup with Conor McGregor (14-2 MMA, 2-0 UFC), and Diego Brandao (18-9 MMA, 4-2 UFC) has agreed to step in as a replacement opponent.

The new matchup now headlines UFC Fight Night 46, which takes place July 19 at The O2 in Dublin. The entire event is expected to stream on UFC Fight Pass in the U.S.

UFC officials today announced the change and revealed that Miller ha suffered torn ligaments in his hand and is currently in a full cast. Despite the change, UFC President remains optimistic the fight will be a barnburner.

“Diego Brandao is explosive and a well-rounded fighter,” White stated. “This should be a war.”

McGregor fights for the first time since he tore his ACL in a winning effort against Max Holloway this past August and was forced into rehab. He’ll have the added pressure of fighting in his native Ireland.

Meanwhile, Brandao returns to action after being forced out of this past weekend’s TUF Brazil 3 Finale event in Brazil. The Brazilian slugger looks to rebound from a loss to Dustin Poirier in December. “The Ultimate Fighter 14” winner badly missed weight (151.5 pounds) for the fight and then suffered a first-round knockout, which halted a three-fight winning streak.
