With so many fights coming up spread across seven different weight classes, it's easy to lose track of what's happening in every division. Here, we take a look at where a particular division stands right now, and where it's headed.

Last week, a bombshell piece of news hit the UFC Welterweight division: dominant champion Georges St. Pierre is injured and a new interim champion will be crowned. It's been nearly 4 years since anyone other than GSP held that belt, and now, some new names finally have a chance to get their foot in the door. Who will make the most of this opening, and who will be waiting for GSP when he returns? Let's see who has a shot.

Next in Line:

At UFC 143 it will be the #3 ranked Nick Diaz vs. #5 Carlos Condit for the Interim Welterweight title. Great fight there, and one that has come about in a very convoluted series of events. What started at GSP vs. Nick Diaz at UFC 137 evolved into GSP vs. Carlos Condit when Diaz famously no-showed his media obligations. Then GSP was hurt, leading to the Diaz vs. B.J. Penn main event. After Diaz won, Diaz vs. GSP was back on, only for it to be switched yet again, this time to today's Diaz vs. Condit. Will we see more switches before February 4? I hope not, as this is a fight that really interests me, but we'll just have to wait and see.

Key Match Ups:

Looking over the division, the loss of the champ actually comes at a rather opportune time. Often when I put these lists together, there are 2 or 3 big fights to highlight. Not so this time. Take a look at the ridiculous action the 170 pounders have in store for us in the coming months:

In The Mix:

Just in case that wasn't enough, here is another handful of fighters who could make a big impact in their next fight:

#15 Rick Story - Poor Story has lost most of the momentum he had mid-year. After beating Thiago Alves and being scheduled to face Nate Marquardt, he looked on the verge of the top 5. He's now on a 2 fight losing streak, but definitely has the skill to get back in contention.

#21 Brian Ebersole - That UFC 140 win over Claude Patrick wasn't pretty, and it won't do his quest for a title shot any favors. But he is still a worthy contender, who should have a good fight next time out.

Others to Consider:

And finally, a few names that may not find themselves in the title picture any time soon, but should be mentioned:
