Tragedy struck yesterday when two bombs exploded during the world-famous Boston Marathon. At the four-hour mark, just as recreational runners were finishing up the race, the bombs went off, killing at least three people, including an 8-year-old boy, and injuring at least 140 people. Our prayers are with the city of Boston and all of the victims.

On the heels of his controversial trip to Cuba with his superstar wife, Beyoncé, ​rapper/mogul Jay-Z created another stir  by announcing his foray into the sports world. It's now official — Jay has partnered with Creative Artists Agency to form Roc Nation Sports. Roc Nation aspires to be a full service sports agency, but thus far Jay appears to be acting as a glorified runner — you know, the guy that recruits on behalf of real Agents. My guess is that CAA hopes that Jay can help them keep their roster full of pre-made stars rather than up-and-comers, which take time to develop and promote. 

Already, Jay's relationship with NY Giants player Victor Cruz has come into question. The Superbowl champion wide receiver signed with Roc Nation after being seen throwing up the Roc sign during the season while already under representation. Sidebar: Grownups are throwing up the Roc in 2013? But I digress…agents asked the National Football League Players' Association, which licenses agents, to look into Jay's relationship with Cruz to see if any runner and tampering rules were violated. So far, it looks like Jay is in the clear. But going forward it's hard to imagine Roc Nation and CAA partnering without incident. 

Moving on to college sports. Now that the NCAA's mens' basketball championship is over, we can get back to roasting them for being hypocrites full-time. The Daily Show took on the NCAA’s silly rules that prohibit college athletes from profiting off of their own name and likeness. The show's correspondent Aasif Mandvi did a fabulous (and hilarious) job of pointing out how ridiculous and frequently damaging the NCAA rules are to the student-athletes it purports to protect. The clip is a must-see.  

Speaking of weird NCAA news, Mike Rice, whose maniacal coaching got him fired from Rutgers, is now coaching 12-year-old girls. According to reports, the parents are totally great with it. I'd object, but there aren't too many demographics tougher than tween girls! Rice may have his hands full.

In other news, Tiger Woods didn't win the Masters –that honor goes to Aussie Adam Scott. But we still spent a good bit of the contest talking about Woods after he accidentally violated the rules on Friday and was dimed out by a viewer. Well, to be fair, Woods actually mentioned the ball-drop violation in his post-game interview. But having a viewer call in to report the violation is definitely one of the most hilarious things I've seen in sports. The Masters rules committee decided not to disqualify Woods but to penalize him two strokes, which was well within their rights. Still, a few hysterical radio hosts and sports writers called on Woods to DQ himself. I'm glad he disappointed them by continuing to play.  

Everyone's favorite Rihanna ex, LA Dodgers Matt Kemp, somehow, some way was not suspended for his role in the mostly verbal baseball brawl with the San Diego Padres. The fighting broke out when Dodgers pitcher Zach Greinke struck Carlos Quentin while he was up to bat. Quentin responded by charging the mound and breaking Greinke's collarbone. Kemp was one of many players who, shall we say, "intervened." Kemp could even be seen after the game in the tunnel confronting Quentin YET AGAIN. Kemp should count his blessings that he is escaping with no penalty. The MLB has suspended Quentin for 8 games and Greinke is slated to miss at least two months recovering from Quentin's linebacker-esque hit to his collarbone. 

That wraps up this week's sports notes. Did we miss anything?
