Both Purdue and Indiana University slid down the college basketball ranks after suffering losses this past week.

Purdue fell from No. 1 to No. 3 in The Associated Press Top 25 men’s college basketball poll and got four first-place votes after suffering its first loss at Rutgers last week. Meanwhile, No. 15 IU fell out of the top 25 after losses to Iowa and Northwestern.

Houston is back at No. 1 for the second time this season, while Kansas State continued its unexpectedly strong start by leaping from unranked to the verge of the top 10.

The Cougars received 34 of 60 first-place votes in Monday’s latest poll to return to the top after a two-week stay there earlier this season. Kansas was second and had 22 first-place votes.

Before this season, the Cougars (16-1) hadn’t been No. 1 since the high-flying “Phi Slama Jama” days of the 1980s.

Alabama and Tennessee gave the Southeastern Conference a pair of top-5 teams, with the Crimson Tide returning to No. 4 for the first time since spending a week there in December and the Volunteers hitting their season high at fifth.

Connecticut, UCLA, Gonzaga, Arizona and Texas rounded out the top 10, with the Longhorns falling four spots after a tumultuous week that included the firing of coach Chris Beard as the coach faces a felony domestic family violence charge.

Then there’s Kansas State, which jumped to No. 11 after an impressive week with two road wins against ranked opponents under first-year coach Jerome Tang. Picked to finish last in the 10-team Big 12, the Wildcats scored 116 points at Texas then edged Baylor 97-95 in overtime.

No. 19 Providence, No. 23 San Diego State and No. 25 Marquette joined Kansas State as the week’s new additions. Baylor, New Mexico and Ohio State fell out of the poll, with Scott Drew’s Bears now unranked for the first time since the 2018-19 season.
