It's do-or-keep-gate time in the 170-pound division as talented but inconsistent veterans Martin Kampmann and Rick Story face off at the upcoming UFC 139 pay-per-view on Nov. 19 in San Jose, California.

Our fiscal friends at Odds Shark have Kampmann as the +115 underdog heading into the HP Pavilion compared to Story's -145 favored betting line.

Kampmann (17-5) is coming off a "Nightmare" decision at UFC on Versus 3 to division wildman Diego Sanchez. His unanimous decision loss to "The Dream" was his second straight defeat -- and the second that could have very easily been scored in his favor.

Prior to his loss to Sanchez, "The Hitman" was edged out by former Strikeforce Middleweight Champion Jake Shields, who wasn't "great" in his Octagon debut but still managed to overcome the Dane.

Also falling on hard times is Story, who is probably eager to erase the "Horror" of his unanimous decision loss to Charlie Brenneman at UFC on Versus 4 back in June.

Story (13-4), who was expected to headline opposite the hormonally-challenged Nate Marquardt, was instead upset by the late-replacement "Spaniard" and sent back to the middle of the pack.

A loss here, for either man, will likely eliminate them from title contention for the foreseeable future.

Who gets back "into the mix" and who goes home?
