Shane Carwin’s blog has the info on his pulling out:

There is no word yet on a replacement opponent for the rotund but skilled Nelson.

By way of MMA Junkie:

Ever since the Shane Carwin steroid story broke there has not been any fighter as outspoken in his criticism of the former heavyweight title challenger than Roy Nelson. The bout between the two heavyweights will be a complete clash of body types and a battle of styles. Carwin is a powerhouse who relies on incredible striking power to finish opponents quickly, Nelson has good power but is also a tremendous fighter from the top on the ground and has cardio beyond what one would assume looking at his rather rotund frame.
