Mac Danzig's representatives made the following announcement on his personal website:

Forget what you heard! Mac is NOT fighting at UFC 87, or in August at all! Mac will most likely fight in September, and the fight has not yet been signed.

A Mac Danzig - Clay Guida match up had been rumored for UFC 87 but appears to be off base. No word yet on whether the match up will still take place, but it appears unlikely to happen at UFC 87.

Danzig, the TUF 6 winner, choked out bjj ace Mark Bocek in his last fight at UFC 83.

Clay Guida is coming off of a solid victory at UFN 13, besting Samy Schiavo via first round knockout.
