The first round of the NCAA Tournament might not have produced the number of upsets some fans were looking for, but Saturday's second-round action got the underdogs back on track.
Sunday's contests could see even more of the same, as there are a number of scary situations for higher-seeded teams.
Indianapolis is going to be the place to watch for potential upsets as No. 2 seeds Louisville and Kentucky both draw difficult matchups in the Midwest and South Regions, respectively.
While the Bluegrass rivals are high on upset alert, a couple of Pac-12 schools should also be on the lookout for a close game as UCLA and Oregon both face stiff tests as No.
