Two sources close to the situation have told MMA Fighting that Shields will eventually make his first foray into the octagon against welterweight contender Martin Kampmann.
This seems like a perfectly fine introductory fight for Shields. Kampmann has fought enough that people know who he is but it should be an entirely winable fight for Jake.
SB Nation will have more on the Jake Shields situation including hopefully confirmation of this bout with Kampmann.
