Two always improving wrestlers are set to meet this September at UFC 151.

Officials within the promotion have announced that Danny Castillo will take on Michael Johnson, in what is expected to be a preliminary bout on the card.

Castillo, who has amassed an impressive 4-1 record inside the octagon, came over from the WEC, and has been a roll since, scoring consecutive wins over Shamar Bailey, Anthony Njokuani and John Cholish. The Team Alpha Male product has put together six victories in his last seven bouts.

Johnson, who looked better than ever when he defeated TUF 14 winner Tony Ferguson, has looked impressive in his own right. The Blackzillian fighter has traded wins and losses inside the UFC, but continuously looks to be improving every time he steps into the cage.

UFC 151 takes place September 1st and features a light heavyweight title bout between champion Jon Jones and challenger Dan Henderson.
