Tyrone Garland banked in a floater with 2.5 seconds remaining, and La Salle beat Mississippi, 76-74, in a thrilling third round game of the 2013 NCAA tournament's West Region on Sunday in Kansas City, Mo. The 13th-seeded Explorers had to win two games just to face the 12th-seeded Rebels, who upset Wisconsin on Friday.
