FAYETTEVILLE, Ark. — Thanks in part to an 81-78 upset win over Arkansas on Saturday, the LSU basketball team will be seeded fourth for the Southeastern Conference tournament that begins Wednesday in Nashville, Tennessee.

LSU had to wait about seven hours after its stunning victory over Arkansas to learn it would have the No. 4 seed and the double-bye that goes with it when Ole Miss dropped an 86-77 decision to Vanderbilt on Saturday night.

LSU, which got a buzzer-beating 3-point shot from Keith Hornsby to shock 18th-ranked Arkansas, gets a pass into the quarterfinal round on Friday.

The Tigers will meet the winner of Thursday’s game between No. 5 seed Texas A&M and the survivor of the tournament opener between 12th-seeded Mississippi State and No. 13 Auburn on Wednesday night.

LSU will take the floor on Friday about 25 minutes after top-seeded Kentucky, which finished the regular season 18-0, opens quarterfinal play at noon.

Georgia and LSU both won on Saturday, the final day of the regular season, while Texas A&M and Ole Miss lost. All four finished 11-7 in league play.

In a tie-breaker based on the winning percentage among all teams involved, Georgia, which was 3-1 against the other three, emerged with the No. 3 seed and LSU (3-2) took the fourth spot. Texas A&M (2-2) got the fifth seed and Ole Miss (1-4) fell to sixth after having a shot to secure the third seed.

If Kentucky and LSU both advance through the quarterfinals, they would meet in the semifinals at noon Saturday. It would be a rematch of their Feb. 10 battle in the Pete Maravich Assembly Center, which Kentucky won 71-69.
