The Final Four could end up all 1s.

The Elite Eight begins out West, with top-seeded Oregon trying to become the first of four one seeds to make the Final Four. The Ducks face player of the year candidate Buddy Hield and No. 2 Oklahoma in Anaheim, California. Oregon has not been to a Final Four since winning the first NCAA Tournament in 1939.

The first game of the night is scheduled to tip off at 6:09 p.m.

The nightcap is another 1 vs 2 matchup, with maybe the most impressive teams of the tournament so far. Top overall seed Kansas and second-seeded Villanova play in the South regional final at Louisville, Kentucky.

The winners are off to Houston for next week's Final Four.

On Sunday, two more one seeds – North Carolina and Virginia – will play. The only time all one seeds played in the Final Four was 2008.
