Demetrious Johnson defended the his flyweight title for the first time at UFC on Fox 6, beating John Dodson in a fast-paced, five-round contest.
There's no clear-cut flyweight contender-in-waiting, and the biggest upcoming fight at 125 pounds is a bout between Joseph Benavidez and Ian McCall—two fighters Johnson defeated in 2012.
Since Johnson had close fights with both of those individuals, there's a good chance a rematch is in order for the champion, but let's take a look at who should be next for "Mighty Mouse" and the rest of the competitors from the UFC on Fox 6 fight card.
Sean Spencer had a rough outing against Rafael Natal at UFC on Fox 6, but the short-notice fight allowed him to get his foot in the door with the world's premier MMA organization.
After making his UFC debut in the middleweight division, Spencer can now return to his natural weight class at 170 pounds.
A matchup with another welterweight coming off of a loss in their first Octagon appearance would make sense, so let's have Spencer meet The Ultimate Fighter: Smashes runner-up Brad Scott in his sophomore showing.
After a loss to Andrew Craig, Rafael Natal took a step back against UFC newcomer Sean Spencer, but a submission win at UFC on Fox 6 should have him back fighting opponents who are coming off of a win inside the Octagon.
Since Derek Brunson likely angered the UFC brass with a lackluster victory over Chris Leben in his UFC debut, he probably won't get a fight with a middleweight contender in his next outing. Instead, a bout with Natal would make sense.
Following losses on Saturday, Mike Stumpf and Simeon Thoresen are coming off of multiple UFC defeats and are in danger of losing their spots on the organization's welterweight roster.
With several fighters set to join the promotion from the Strikeforce merger, the UFC needs to continue trimming fighters from its ranks.
A bout between Stumpf and Thoreson later this year would lessen the UFC's load by one.
Aside from a loss to borderline contender John Hathaway, Pascal Krauss has looked like a fighter who has a bright future in the UFC's 170-pound division.
More importantly, Krauss could play a big role in the UFC's expansion into Germany and the rest of eastern Europe.
Thus, the organization should look to build "Panzer" up with a winnable fight against fellow UFC on Fox 6 competitor David Mitchell instead of throwing him to the wolves again.
Chicago police officer Mike Russow disappointed in his hometown at UFC on Fox 6.
Despite a strong start against Shawn Jordan, Russow faded in the second round and was stopped with strikes late in the stanza.
A bout with Dave Herman, who is eligible to return in April from a failed drug test, would give Russow a reasonable chance to avoid a third straight defeat.
Shawn Jordan's performance against Mike Russow at UFC on Fox 6 was far from flawless, but his conditioning helped him to get the job done with a second-round stoppage.
A recent loss to Cheick Kongo hurt, but Jordan has time to earn another shot against a fringe contender in the UFC's heavyweight division. With two UFC wins following a temporary retirement, Gabriel Gonzaga is hoping for that same opportunity.
Let's see Jordan and Gonzaga square off with a step up in competition on the line.
Vladimir Matyushenko looked 42 years old against Ryan Bader on Saturday, and that's probably because he has indeed existed for 42 years.
It's no secret Matyushenko's career is winding down, but he won't want to go out with the performance he had at UFC on Fox 6.
While it wouldn't be the most highly anticipated rematch in MMA history, a bout with Igor Pokrajac, who he defeated more than three years ago, would give Matyushenko a chance to finish his career with a win.
It was controversial, but Clay Guida was able to pick up an important win over Hatsu Hioki in his featherweight debut.
Though the victory makes him a contender in the 145-pound division, the debatable nature of his win means he's not deserving of a fight with a top contender like Ricardo Lamas or Chan Sung Jung.
A fight with another former lightweight wrestler in Nik Lentz would be more likely, and could force both fighters into a rare stand-up contest.
Surging upward in the lightweight division, T.J. Grant notched the biggest win of his career at UFC on Fox 6, a first-round stoppage via elbows against Matt Wiman.
This was a huge victory for Grant, but he'll probably have to build up his name with one more win before he is given the opportunity to fight a top-five lightweight.
A matchup with Jamie Varner has Fight of the Night written all over it and would be deserving of a spot on the main card of a big event.
Following a lengthy hiatus due to injury, Erik Koch was not at the top of his game at UFC on Fox 6, where he was knocked out by Ricardo Lamas.
Hatsu Hioki had a bit more success in his fight on Saturday, but he too came up short in a decision with Clay Guida.
In the featherweight division, there are a number of contenders waiting for their shot at the belt right now. However, that pack of elite 145-pound fighters could be narrowed down quickly, and the UFC will want Koch or Hioki back in the mix when it is.
A fight between the two would ensure one fighter gets back in the chase for a championship bout in a hurry.
With four straight wins against tough featherweight competition, Ricardo Lamas has separated himself as one of the top contenders in the 145-pound division.
There is some strong support for Chan Sung Jung to meet the winner of an upcoming title fight between Jose Aldo and Frankie Edgar, but "The Korean Zombie" hasn't won since May, and Lamas has picked up two huge victories since then.
Fighting one week before Aldo and Edgar, Lamas' timetable for a return to the cage should align with the eventual champion, while Jung would have to continue to sit on the shelf unnecessarily.
After losing to T.J. Grant in the way that he did, Matt Wiman wouldn't normally be given a fight with Donald Cerrone. However, Cerrone was also beaten badly at UFC on Fox 6, and the UFC will want to give the star lightweight a winnable fight to get him back on track.
While he's not on Cerrone's level in terms of ranking in the lightweight division, Wiman is an entertaining fighter and one who can usually hang tough with highly skilled 155-pound opponents despite his poor outing against Grant on Saturday.
Former Strikeforce champion Gilbert Melendez is an intriguing challenger to Benson Henderson's lightweight throne, but the UFC probably should have waited until after UFC on Fox 6 to determine the next top contender in the 155-pound division.
In breezing through Donald Cerrone, Anthony Pettis showed he's the most deserving lightweight of a shot at UFC gold, and a rematch with Henderson is a fight fans have been waiting for since the UFC-WEC merger.
The call is easy here. Pettis should wait and fight the winner of that April bout between Henderson and Melendez.
Glover Teixeira proved he's more than just a prospect against Quinton Jackson on Saturday, but his win wasn't one that makes him deserving of a title shot or even a fight with one of the top contenders in the light heavyweight division.
With a fellow heavy hitter like Ryan Bader coming off of an impressive win at the same event, it would seem to make sense for Teixeira to meet the TUF winner in his next appearance.
If Teixeira can beat Bader, who also holds a decision win over Jackson, then a serious case can be made for the Brazilian to fight a top-five light heavyweight.
John Dodson came up short in his first UFC title fight, but the punching power he showed in the second round of that bout leads one to believe it won't be the last championship bout of his career.
With an important flyweight bout between Joseph Benavidez and Ian McCall upcoming, Dodson could meet the loser of that contest in a matchup that would give the TUF winner a good opportunity to bounce right back into title contention.
Demetrious Johnson has his first flyweight title defense out of the way, but there is already a lack of fresh challenges for the 125-pound champion.
No flyweight stands out as overly deserving of a title shot right now, and the biggest bout on the horizon is one that features two competitors Johnson defeated in 2012—Joseph Benavidez and Ian McCall.
While not ideal, a rematch with either one of those fighters would be justifiable, as they both gave "Mighty Mouse" close fights. So, it looks like the winner of that matchup between Benavidez and McCall will get another crack at Johnson.
