Ryan LaFlare has been forced out of a planned welterweight showdown with Gunnar Nelson for UFC Fight Night: McGregor vs. Miller. In his place will step Zak Cummings.

Set for July 19, the event takes place inside the O2 Arena in Dublin, Ireland. The main event features Conor McGregor returning from knee surgery to meet Cole Miller in a featherweight battle.

Cummings (17-3) has picked up two straight wins inside the Octagon to push his overall win streak to four in a row. The alum of The Ultimate Fighter earned a decision over Yan Cabral earlier this month after submitting Ben Alloway last August.

The submission win for Cummings over Alloway marked his third straight victory via form of choke before going the distance with Cabral. He was originally scheduled to face Kenny Robertson three days earlier. Officials are searching for a replacement to meet Robertson at this time.

Nelson (12-0-1) has won all three of his UFC fights, including submission wins vs. Omari Akhmedov and DaMarques Johnson. In between, he scored a decision over Jorge Santiago.

This fight marks the first time since 2010 that Nelson has competed at least twice in the same calendar year. He’s had several opponents pull out of planned fights since signing with the UFC.

Other bouts scheduled for the card include Brad Pickett-Ian McCall and Neil Seery-Phil Harris in two flyweight bouts, along with middleweights Tom Lawlor and Cody Donovan.
