How Melvin Guillard would fare against Nate Diaz is not a question that’s kept a lot of observers up at night: the New Orleans native is probably going to get twisted into a neat little knot. But a free altercation is a free altercation, and the latest Spike TV broadcast to kick off the latest season of “The Ultimate Fighter” has an undercard worth tuning in for.

What: UFC Fight Night 19: Diaz vs. Guillard, an 11-bout card from the Cox Convention Center in Oklahoma City, Okla.

When: Wednesday, September 16 at 8 p.m. ET on Spike TV.

Why You Should Care: Because there’s no telling which Roger Huerta will show up against Gray Maynard -- flat contract completist, or animal; because Tim Credeur has quietly built up a perfect 3-0 record in the promotion and could see that punctured by Nate Quarry; and because everyone is sleeping on Brock Larson, owner of fast-twitch muscle fibers and athletic enough to give anyone in the welterweight division a sleepless night.

Fight of the Night: If their first two fights are any indication, Steve Cantwell vs. Brian Stann is destined to be a four-ounce gloved boxing match.

Preemptive Complaint: Larson, 26-2, exciting and undefeated for two years, is still a “may not be broadcast” athlete? Good Lord.
