UFC officials broke the news last night via twitter.
UFC on FOX 3 is set to take place in New Jersey from the IZOD Center in East Rutherford on May 5. In the main event lightweights Nate Diaz and Jim Miller will throw down in a five-round non-title fight.
The two welterweights were originally booked to square off at UFC 138 but in the end, both fighters were forced to withdraw with injuries.
At UFC Fight Night 24 Hathaway fought and beat Kris McCray via split-decision. By the time his UFC on FOX comes he will have been on the shelf for 14-months. The McCray victory bounced him back from his only career defeat to Mike Pyle at UFC 120.
Krauss is a German based fighter who goes in to the fight with an unblemished record. He made his UFC debut at UFC 122 with a decision win over Mark Scanlon.
This bout is likely to appear on the preliminary portion of the card.
The UFC on FOX 3 card now includes the following:
Nate Diaz vs. Jim Miller
Pat Barry vs. Lavar Johnson
John Hathaway vs. Pascal Krauss
John Dodson vs. Darren Uyenoyama
Mike Massenzio vs. Karlos Vemola
Louis Gaudinot vs. John Lineker
