Duke, Michigan, Tennessee and Virginia remain in the top four spots of The Associated Press men's college basketball poll.

The Blue Devils received 37 of 64 first-place votes from a media panel in the AP Top 25 released Monday. No. 2 Michigan received nine first-place votes, No. 3 Tennessee 13 and No. 4 Virginia five.
No. 5 Gonzaga, Michigan State, Kansas, Texas Tech, Virginia Tech and Nevada rounded out the top 10.
Kansas dropped two spots after losing to Iowa State, which moved into the poll at No. 20. Nevada and No. 13 Florida State each fell four spots after losing.
