Once upon a time, it looked like Tiger Woods was pretty much a lock to break Jack Nicklaus' record of 18 major championships. People weren't sure how quickly he was going to be able to do it. But the consensus was that he would do it one day. He was too talented not to.

But now, after failing to win a major in 2013 for the fifth consecutive year, Woods' chances of breaking Nicklaus' record are in serious doubt. And they took a pretty significant hit early last week when Woods, seemingly out of nowhere, announced that he would not be taking part in the Masters this year after undergoing back surgery. We knew that Woods had been suffering from back issues for several months now. But we didn't know that his back had gotten so bad that he needed to have surgery. And we definitely didn't know that his back was going to sideline him for at least the next few months, which will severely limit his chances of winning a major during the next calendar year. It sucks for Tiger, his fans, and the entire sports world.

Tiger isn't the only sports-related person who hit a rough patch last week, though. Several other high-profile athletes did, too. From an MLB player who got killed by the media for taking "paternity leave" and missing two games to an NBA player who got suspended for five games after testing positive for marijuana, these are the 10 Sports People Who Had a Worse Week Than You.
