LAWRENCE, Kansas — Donovan Jackson says he called his shot. 

While huddled together with the rest of his team during a timeout with 46 seconds left in overtime, Jackson and the Cyclones were up by one against No. 3 Kansas at Allen Fieldhouse on Saturday.

Iowa State had possession, and Jackson — a 3-point specialist — was ready to make his mark.

“Watch this,” Jackson screamed toward his teammates as play was getting ready to resume. “Watch this.” 

On the very next play, point guard Monté Morris, Jackson’s roommate, drove the ball into the lane but ran into a wall of Kansas big men. He kicked it out to Jackson, who was camped out in the corner, ready to fire. 

Jackson received the ball and launched.

Allen Fieldhouse went silent.

Jackson had made the biggest shot of his short career and gestured toward the bench in celebration.  

Jackson’s 3-pointer propelled the Cyclones (14-8, 6-4 Big 12) to a 92-89 victory over the Jayhawks (20-3, 8-2 Big 12) on the road — the team’s first win at Allen Fieldhouse since 2005 and Kansas coach Bill Self’s 10th career loss at home. 

It also snapped a 51-game winning streak at Allen Fieldhouse for Kansas. 

“We were just the fortunate team tonight,” Morris said, who had lost three times at Allen Fieldhouse previously. “It could’ve went either way. They made shots. We missed some. And vice versa. But today was amazing. A very emotional day for myself and the seniors along the way. We’ve come close every year.” 

Iowa State legend Georges Niang, who graduated from Iowa State last year, never won on the road against Kansas. Many Cyclones haven’t. 

So before the game, assistant coach William Small gathered the team and dedicated the game to past alumni who could never find the coveted win at the infamous arena. 

“We’re a family,” said Jackson, who was playing in his first game at Allen Fieldhouse. “This means a lot to us. I’m just real happy and excited that the seniors got the opportunity to win here. I don’t think Georges Niang got the opportunity to win here. We said this in the locker room that this was for him.”

But Iowa State’s opportunity for that victory looked doomed from the start.

Entering the game as a 10.5-point underdog, the Cyclones came out lethargic. The defense struggled to slow down the high-powered Jayhawk offense as Kansas shot 70 percent from the field and out-rebounded Iowa State 19-3. The Cyclones trailed 52-38 at halftime. 

“Frustrating. Disappointing,” Prohm said about mood at the break. “[But] our guys responded. And there’s no other better place in a America to respond than Allen Fieldhouse as a road team.” 

Forward Deonte Burton, who had 10 points in the first half, kickstarted a comeback effort for the Cyclones, putting up 16 second-half points on 6-of-12 shooting. Iowa State chipped away at the Kansas lead and pulled ahead with over six minutes to play. 

While the clock continued to trickle down, Iowa State continued to trade blows with Kansas. The Jayhawks had more than a few chances to pull ahead, but each time they made a mistake or missed a shot, giving Iowa State the chances it needed. 

Iowa State eventually forced Kansas’ Frank Mason III, who had a career-high 32 points Saturday, to miss the game-winning shot, sending the game into overtime tied at 82. 

Again, it came down to the wire. Iowa State finally found a way to pull ahead thanks to a quick basket followed by Jackson’s 3-pointer. Kansas was still able to pull within one.

They sent Morris, who entered the game with a 82.8 percent free throw percentage, to the line. 

He had made bigs shots before. Just not in this arena. 

 “Just make the two free throws,” Morris said about his mentality. “Nothing else was going through my head. I was just focused on the rim and make my shots.” 

He did.

As the Kansas fans slowly filtered out of Allen Fieldhouse, the cheers of the well-traveled Cyclone fanbase started to become more evident as the seconds ticked off the clock. 

After Kansas’ Svi Mykhailiuk missed a potential game-tying 3-pointer, it was official. Iowa State become the only team to win more than once at Allen Fieldhouse.

And it couldn’t have come at a more opportune time. 

Before this week, the Cyclones had lost by a combined nine points to ranked opponents. On Tuesday, they lost by double-digits to No. 7 West Virginia. They lacked a resume win for the NCAA Tournament committee. 

No longer.

“It’s a tough business, man,” Prohm said, his voice wavering. “We’ve come so close so many times this year. You do this because you want to see your kids be happy. For Monté and Naz [Mitrou-Long] and those guys — you don’t want to let those guys down.”
