About a month ago, we reported that Aaron Simpson was dropping to welterweight and would be facing Jon Fitch in his debut. The fight was expected to be taking place at UFC 149 on July 21st at that point, but it got switched up. Simpson tweeted the date and channel the fight would be on, which works out to UFC on Fuel 4:

July 11th on Fuel TV. Trainin' hard!

It is unclear whether the fight will be shown on the main card or not at this point, but you'd have to expect that it would be. Simpson went 6-3 as a middleweight in the UFC, but decided to drop down due to the size difference between himself and regular middleweights. He'll meet Fitch, who was a middleweight at one point as well and is winless in his last two bouts.

The main event of the card is a five-round middleweight battle between Chris Weidman and Mark Munoz.
