Mike Tyson today. (Getty Images)Mike Tyson is enjoying a career resurgence, a second (third?) chapter in his life in which the former heavyweight champion is proving to be far sharper and funnier than we'd given him credit for back during his boxing days.

He's reshaped his image with a memorable cameo in "The Hangover" (you can't hear "In The Air Tonight" without doing Tyson drums anymore, can you?), a one-man show ("The Undisputed Truth") and appearances on shows like "Law & Order." And now he's trying to address some of his financial matters. He's filed suit against SFX Financial Advisory Management Enterprises, a financial services firm owned by Live Nation, charging that one of its advisers embezzled more than $300,000 from him, as well as cost him millions in potential future earnings.

Tyson's suit claims that SFX has not given Tyson a complete picture of the embezzled money, and while SFX has returned some of the money, has asked Tyson to sign a nondisclosure agreement. Tyson's suit seeks more than $5 million

Juan Manuel Marquez (L) goes to a corner after knocking out Manny Pacquiao (Getty)In 2011 when Manny Pacquiao won a tight decision over Juan Manuel Marquez in the third fight between them, Pacquiao's zealous supporters weren't simply content to see their man get a win many experts didn't believe he deserved.

In the days following that Nov. 12, 2011, bout, Pacquiao's fans took to the Internet in droves to post photos that showed Marquez stepping on their hero's foot. It didn't matter that Pacquiao had won or that such an occurrence is common when a left-hander such as Pacquiao fights a right-hander like Marquez. They referred to it as "foot stomping" and implied it was the reason the fight was even close.

The Pacquiao fans had to bellyache about it as a way to try to explain why he didn't win more clearly. That point of view clearly disregarded the fact that each of their first two bouts were exceptionally close.

Juan Manuel Lopez tries to get up on March 10 after being knocked down by Orlando Salido (AP)

Juan Manuel Lopez has long been one of the game's most exciting fighters, and he's often too brave for his own good. He loves to stand toe-to-toe and slug in the hopes of bringing the fans out of their seats.

Mostly, it's worked for him as he's compiled a 31-2 record with 28 knockouts and world titles at super bantamweight and featherweight.

But it nearly cost him a loss in an epic 2009 scrap with Rogers Mtagwa, when he was barely able to stand in the waning seconds. And he dropped a pair of bouts in the last year to Orlando Salido.

Lopez was suspended after the second loss to Salido for making allegations that referee Roberto Ramirez was gambling. Lopez was clearly woozy after that March 10 loss but was interviewed within seconds after the fight's 10th-round stoppage.

Juan Manuel Lopez (AP)Lopez's words were wrong and he had nothing to back up his accusation that Ramirez has a gambling problem. But he'd also recently been concussed and
