Struve (22-5) is coming off a second round submission win over Pat Barry in October and has won three of his last four fights. The 23-year-old has been in the UFC since early 2009 and has a 6-3 Octagon mark.
Herman (21-2) made his UFC debut in June, earning Fight Of The Night honors in a second round TKO win over Jon Olav Einemo at UFC 131. He's been on the shelf since testing positive for marijuana before his scheduled October UFC 136 tilt with Mike Russow.
The 27-year-old denied any usage of the drug and has tested in the clear several times since his violation, clearing the way for him to return. He's won three straight and six of his last seven with five finishes to his credit.
