Though the weekend was dominated by some title fight in Atlanta, Friday night's Bellator and "The Ultimate Fighter" bouts brought plenty of excitement, both during and after the fights.

At Bellator, Eddie Alvarez made quick work of Shinya Aoki in their rematch, as Aoki had no answer for Alvarez's striking. Aoki's corner threw in the towel seconds before the match was stopped two minutes into the first round.

As shown in the video above, Andreas Spang took out Brian Rogers with a left hook in the second round after Rogers had been winning the bout. Afterwards, Spang gave the crowd in Cleveland two middle fingers and got in a scrap with Maiquel Falcao. Though he expects to be disciplined by the Ohio Athletic Commission, his spot in the middleweight tourney is safe.

He'll face Falcao there after Falcao earned his spot by outlasting Vyacheslav Vasilevsky to a split decision. In the lightweight tournament, Rick Hawn took just a round and 10 seconds to knock out Lloyd Woodard, while Brent Weedman took a split decision from Thiago Michel.

On TUF, Vinc Pichel and John Cofer turned in a three-round decision that was one of the best fights of the season. The first round featured stand-up which could have gone to either fighter, while Pichel's grappling gave him the second. In the third, Pichel got a quick takedown and arm triangle choke to get the win for Team Cruz. On Friday, Sam Sicilia from Team Cruz will fight Team Faber's Chris Saunders.

Alistair Overeem said medication caused a failed drug test on March 27 (AP)

Hulking heavyweight Alistair Overeem, who lost a shot at the UFC heavyweight title when he failed a March 27 random drug test administered to him by the Nevada Athletic Commission, said in a statement Monday released by his management team that the reason for his failure was medication he was given to treat a rib injury.

Overeem, who had a 14:1 testosterone-to-epitestosterone ratio that was more than twice the legal limit of 6:1 in Nevada, was on Friday pulled from the title fight against champion Junior dos Santos that was to be the main event of UFC 146 on May 26 in Las Vegas by UFC president Dana White and replaced by Frank Mir.

The failure was first announced by the Nevada commission on April 4, noting that Overeem's T/E ratio exceeded 10:1. The next day, it announced that the exact number was 14:1.

Overeem had a hearing scheduled in front of the Nevada commission on Tuesday, but White said

Browne celebrates after win. (Tracy Lee)UFC 145 was a top-heavy card, with most of the pre-fight discussion focused on the main event of Rashad Evans vs. Jon Jones. However, some of the undercard still managed to stand out with memorable performances.

No. 1 star -- Michael McDonald: The bantamweight continued his undefeated UFC run with a first-round knockout of one-time WEC champ Miguel Torres. After the fight, he showed true class by sending several tweets to Torres to thank him for the fight.

No. 2 star -- Ben Rothwell: When Rothwell weighed in, he showed off a sleeker shape than he's ever had in the Octagon. He then proved the new body was not just for looks as he knocked out Brendan Schaub in just over a minute.

No. 3 star -- Travis Browne: "Hapa" saved the preliminary card from being all decisions by ruining Chad Griggs' UFC debut. Browne used knees to knock Griggs down, then a beautiful arm triangle to submit Griggs in the first

(Getty)When Frank Mir was given a title shot at UFC 146 in place of Alistair Overeem, several dominoes started to fall in the UFC heavyweight division. Mir was supposed to face Cain Velasquez in Las Vegas on May 26. Since he's fighting Junior dos Santos, Velasquez will face Antonio "Big Foot" Silva, who will be making his UFC debut after a career in Strikeforce and Elite XC. Roy Nelson, who was supposed to fight Silva, is now opponent-less, but is expected to remain on the card.

Got that?

As it stands now, UFC 146 still has an all-heavyweight main card, but the UFC has to scramble to find an opponent for Nelson for a bout that is just 34 days away. Here are all the main card bouts:

Junior Dos Santos vs. Frank Mir
Antonio Silva vs. Cain Velasquez
Roy Nelson vs. TBA
Shane Del Rosario vs. Gabriel Gonzaga
Mark Hunt vs. Stefan Struve

After Jon Jones defended the UFC light heavyweight belt with a win over Rashad Evans, questions immediately turned to his next opponent. At Saturday's post-fight press conference, UFC president Dana White confirmed Dan Henderson would get the next shot at trying to unseat Jones.

This title shot comes after Henderson had a banner year in 2011. He won the Strikeforce light heavyweight belt, beat MMA legend Fedor Emelianenko, then returned to the UFC with a win over Mauricio "Shogun" Rua in a fight that's considered one of the best of all time.

It will be Henderson's third chance to win the UFC belt. After winning titles in Pride, Henderson lost UFC title shots to Anderson Silva at middleweight and Quinton "Rampage" Jackson at light heavyweight. Back in 1998, Henderson won the UFC middleweight tournament at UFC 17, but that is the only UFC title he's won in his 15-year MMA career.

Though White didn't nail down a date for the Jones-Henderson bout, UFC 149 in Calgary was mentioned as a possibility.

After defending the UFC light heavyweight belt on Saturday over Rashad Evans, Jon Jones said he had a new respect for his former training partner and friend.

"I would say Rashad is my toughest fight to date, and a lot of it is because of how talented and awesome of a fighter he is," Jones said after beating Evans in a five-round decision.

Jon Jones kept his UFC championship belt at UFC 145 on Saturday night by beating Rashad Evans, but he couldn't hold onto it for much longer. Chandler Jones, a prospect in this week's NFL draft and Jon's baby brother, tweeted a picture of Jon with the belt. Minutes later, Chandler had it on.
