Nate Diaz vs. Matt Brown has been added to what UFC is attempting to push as its biggest show of the year: UFC 189 on 7/11 in Las Vegas. That show already has featherweight champion Jose Aldo vs. Conor McGregor, welterweight champion Robbie Lawler vs. Rory MacDonald, Gunnar Nelson vs. John Hathaway, Brandon Thatch vs. John Howard, and a lot more.
In addition, Frank Mir vs. Todd Duffee was announced for UFC Fight Night: San Diego on 7/15, and is expected to be the main event. That show already features Josh Thomson vs. the surging Tony Ferguson.
There are three UFC shows and one Invicta show over a six day period that week including shows on Friday, Saturday and Sunday night, all in Las Vegas. In total, UFC is scheduled to have six shows in July.
