The Tigers began the season with high hopes, being ranked #4 in the Associated Press pre-season polls. They stayed in the Top 10 for most of the season until, after Auburn's 68-64 loss on February 22, 2000 to Alabama, it was discovered star forward Chris Porter had accepted money from an agent.[2] Porter was suspended for the remainder of the regular season, the SEC tournament, and the NCAA tournament.
The Tigers finished the 1998–99 season 29–4, 14–2 in SEC play to win the SEC regular season championship. As the top seed out of the West division in the SEC tournament, the Tigers defeated Alabama to advance to the semifinals of the SEC tournament where they lost to Kentucky.

They defeated Winthrop and Oklahoma State to advance to the program's first Sweet Sixteen since 1986, where they lost to Ohio State.[3]
