UNDATED (AP) — The Indiana Hoosiers are No. 1 in The Associated Press men's basketball poll for the fourth straight week. They could find themselves elsewhere in the poll next week following Tuesday's 77-73 loss at Minnesota.

Trevor Mbakwe (ehm-BAHK'-way) had 21 points and 12 rebounds while outplaying Cody Zeller, who committed four turnovers and was held to nine points. Mbakwe helped the Gophers outrebound the Hoosiers 44-30.

Victor Oladipo (oh-lah-DEE'-poh) scored 16 points, but 14 of the 17 points by Jordan Hulls came before halftime.

The Gophers are 19-9 overall and 7-8 in the Big Ten. Indiana is 24-4, 12-3 in the conference.

Eighth-ranked Florida also fell on Tuesday. Jordan McRae scored 27 points and Tennessee boosted its NCAA tournament hopes by knocking off the Gators 64-58. Jarnell Stokes had eight points and 14 rebounds as the Vols picked up their sixth straight win and improved to 9-6 in the SEC.

In other top-25 action:

— Sam Dekker came off the bench to match his career high of 19 points and lead 17th-ranked Wisconsin's 77-46 romp over Nebraska. Ryan Evans added 14 points and Ben Brust had 13 as the Badgers pulled within one game of Indiana for the Big Ten lead.

— No. 19 Memphis erased a 13-point deficit before Brad Redford hit a long three-pointer to push Xavier past the Tigers 64-62. Memphis scored a season-low 20 points in the first half and ended an 18-game winning streak that was tied with Akron for the longest in the nation.

DALLAS (AP) — The Big 12 believes the Kansas Jayhawks received a little unintentional help from the officials Monday night.

The conference says officiating errors were made at the end of regulation as the sixth-ranked Jayhawks outlasted Iowa State in overtime. The league said Tuesday that "appropriate measures will be taken" against the two officials involved, including an adjustment of "the number of future assignments."

The Big 12 did not identify the officials or the plays in question.

The Jayhawks' Elijah Johnson drove into the lane and got tangled up with Iowa State's Georges Niang with less than 10 seconds left. No foul was called, and Niang was then whistled for fouling Johnson on the floor. Johnson sank two free throws with 4.9 seconds left to force OT.
