(Undated) — The majority of NCAA Tournament brackets have been busted. 15th-seeded Princeton pulled off a shocking 59-55 upset of second-seeded Arizona in the South Region. 13th-seed Furman also advanced in the South after knocking off fourth-seeded Virginia 68-67. In the East, fourth-seeded Tennessee fended off a late rally by 13th-seeded Louisiana to stay alive. It was also a dominant showing from the number-one seeds as Alabama, Kansas and Houston all advanced to the second round. The action continues today with top-seeded Purdue taking on 16th-seeded Fairleigh Dickinson in the East Region.
