Guida had a new hairdo, the result of Maynard demanding he not be allowed to let his hair flow freely.
But the biggest change was one Guida's handlers made on their own. They chose not to engage Maynard and it led to Guida being on the short end of a split decision.
Two judges scored the fight for Maynard 48-47, while the third had it for Guida, 48-47. ESPN.com had Maynard winning, 48-47.
Guida was on his bicycle from the opening round. He never stopped moving his head, which at first seemed OK with the fans in attendance at Revel Resort and Casino.
By the third round, however, Guida was literally running around the cage, which didn't sit well with fans or Maynard.
The cheers Guida received early in the fight quickly turned to boos. And chants of Maynard, Maynard, Maynard began spreading through the arena.
"I thought Guida was coming to fight," said Maynard, who improved 12-1-1. "I came to fight. I came to prove to people I could go a hard five."
In the fifth, referee Dan Miragliotta decided he had seen enough and reprimanded Guida for failing to engage Maynard.
With a win in his first fight since suffering a TKO loss to Frankie Edgar in October 2011, Maynard turned his attention to a possible fourth showdown with the former 155-pound champion.
"I want that belt," Maynard said. "I want Frankie Edgar, if he takes care of business with [Benson] Henderson.
"I think there should be a fourth fight."
Guida suffered his second loss in a row. He lost a unanimous decision to Henderson on Dec. 12, 2011.
Like Maynard, Guida (29-20) was hoping a win would land him a title shot against the Henderson-Edgar winner.
Henderson is the current UFC lightweight champion.
Active Stout hands Fisher fifth loss in six bouts
The two exchanged punches and a few kicks nonstop and when the dust settled, Stout had won for the third time in four fights.
All three judges scored the fight 30-27, while ESPN.com had it 29-28 for Stout.
Stout (19-7-1) threw right and left hands throughout, but it was the takedowns that set him apart from Fisher. He landed takedowns in each of the three rounds.
Fisher (25-9) has dropped five of his past six fights. At 36, his future in the UFC could come up for discussion among the promotion's decision makers.
Ebersole gets off canvas to defeat Waldburger
With three wins inside the Octagon, Brian Ebersole entered his bout against TJ Waldburger determined to get people talking about him as a possible welterweight contender.

All three judges had it 29-28 for Ebersole. ESPN.com also scored the fight 29-28 for Ebersole, who improves to 50-14-1 with one no contest.
Waldburger had his winning streak halted at two. He is now 15-7.
Swanson uses speed, left hook to stop Pearson
There is only one reason Ross Pearson went down to featherweight, and that's to contend for a title shot.
He was hoping to take the next step toward that quest against highly respected Cub Swanson. But with six victories in his past seven fights, Swanson also envisions himself in a title bout.
Pearson, a former lightweight, is large for the 145-pound division, but Swanson proved that speed can serve as a viable counter.
Swanson used his superior speed to land punches and kicks that left Pearson's left eye swollen and his face bloody. But a left hook proved to be the most devastating blow.
Swanson landed the punch at 4:14 of the second round, enabling Swanson to improve to 17-5. Now he is talking title shot.
"I was hitting him with a lot of shots but he didn't look like he was hurt at all," Swanson said. "I expect a real good fight (next), maybe a No. 1 contender ship."
Pearson slips to 1-1 as a featherweight. He is 15-6.
