No. 20 Illinois locked up a share of the Big Ten regular-season title when Kofi Cockburn had 21 points and 14 rebounds to lead a 74-72 win over No. 24 Iowa Sunday night.

The Fighting Illini’s hopes for a conference crown were kept alive when Nebraska upset No. 10 Wisconsin earlier Sunday. They didn’t let the opportunity go to waste, claiming at least a share of the Big Ten championship for the first time since winning it in 2004 and ’05.

Illinois (22-8, 15-5) erased a 15-point first-half deficit, but Alfonso Plummer led the charge back en route to 15 points. Coleman Hawkins added nine points and 11 rebounds.

Iowa (22-9, 12-8) missed five of its first six shots but eventually got on a 13-0 scoring run. The burst started with Kris Murray’s 3, the first of nine straight made shots for the Hawkeyes. Peyton Sandfort hit a 3 and then made another jumper on the next possession before Tony Perkins’ layup put Iowa ahead 32-19.

Plummer revived Illinois’ offense with back-to-back 3s, and the Illini closed the half on a 9-0 run as Plummer drove and scored with 4 seconds left to make it a 43-37 deficit.

Hawkins hit a 3 to put Illinois in front 65-63 with 7:03 to go, and they didn’t trail again.

Keegan Murray had 22 points and 11 rebounds for the Hawkeyes, while Perkins had 17 points and 12 boards. Kris Murray added 13 points.

Curbelo had 14 points and six assists off the bench for Illinois.

No one will enter the Big Ten tournament in Indianapolis feeling as good as the Illini, who have won three games in a row and will take the No. 1 seed after holding the tiebreaker over Wisconsin due to an 80-67 win over the Badgers on Feb. 2. The Illini will be in action Friday in Indianapolis.
