Promoter sues Mayweather adviser — Longtime promoter Bob Arum’s company, Top Rank Inc., filed a federal antitrust lawsuit against fellow promoter and Floyd Mayweather Jr. adviser Al Haymon on Wednesday morning. Arum is seeking more than $100 million in damages and is asking the court for an injunction to halt Haymon’s mounting takeover of boxing. Haymon is the brains behind Premier Boxing Champions, a series that launched this spring and managed to put the sport on broadcast television across the country nearly every week. Boxing observers have noted that Haymon appears to be attempting to consolidate the entire sport.

IndyCar CEO: Rules package was off — The CEO of IndyCar said Wednesday that the series went too far with the rules package for last weekend’s race in California, where many drivers sharply criticized what they said was dangerous pack racing. Despite the admission, chief executive Mark Miles warned that criticism of IndyCar by its teams and drivers wil not be tolerated going forward. There were multiple complaints Saturday about the dangers of pack racing on an oval track, with competitors questioning the safety and evoking the 2011 crash in Las Vegas that killed Dan Wheldon. A short time later, IndyCar fined defending series champion Will Power $25,000 and placed him on probation for the rest of the season for directing improper language or gestures at a series official. Power shoved a medical worker after a late-race crash, and he later told the reporters the racing was “crazy.”
