BLOOMINGTON, Ind. (AP) -- Mike Davis wasn't even sure Marco

Killingsworth could play Tuesday night. Fortunately for Indiana,

Killingsworth's back proved strong enough to carry the Hoosiers.

Killingsworth overcame pregame back spasms to dominate the

middle in the second half, and Roderick Wilmont added 17 points as

the Hoosiers (No. 11 ESPN/USA Today, No. 13 AP) upset Illinois (No. 5 ESPN/USA Today, No. 7 AP) 62-60.

"I didn't even think he could go," Davis said. "But he fought

through it and played a great second half."

The Fighting Illini (16-2, 2-2) had no answer for the Hoosiers'

tandem.

Wilmont provided the spark in the first half after Indiana fell

into an early 11-point hole. Killingsworth scored 20 of his 23

points in the second half and added 12 rebounds, one assist and

four blocks.

But Wilmont was every bit as impressive. He tied a season high

with 17 points, matched his career-high with nine rebounds and

sparked an 18-0 first-half run that gave Indiana the momentum it

needed.

After the game, Hoosiers fans poured onto the court, setting off

a celebration that even Killingsworth joined.

"I jumped right in there because I ain't used to seeing that,"

said Killingsworth, a fifth-year senior who transferred to Indiana

from Auburn. "So I jumped in there with them."

For Illinois, it was a rare bad night.

The Illini entered Tuesday with 55 wins in their last 57

regular-season games. They'd beaten Indiana five straight times and

have now lost to only four Big Ten teams since Jan. 24, 2004 --

Iowa, Ohio State, Wisconsin and Indiana.

Shaun Pruitt led the Illini with a career-high 17 points. Brian

Randle added 15 and James Augustine had 11. Dee Brown, Illinois'

top player, was limited to five points but had 11 assists before

fouling out.

And Illinois has now lost two of its last three, while Indiana

has won 11 straight conference games at home.

"Marco's a good player and sooner or later he's going to get

some things," Illinois coach Bruce Weber said. "In the first half

we did a good job fighting him, but it's tough. He's just good."

Killingsworth needed more than solid play to produce against

Illinois, though.

He asked to be taken out just 59 seconds into the game, then

struggled to get going when he returned. When he did post up, shots

weren't falling. And without their big man, the Hoosiers looked out

of sync. Just eight minutes into the game, Indiana had committed

seven turnovers and already trailed 14-3.

That's when Wilmont provided the spark.

He hit two straight 3-pointers to get the Hoosiers righted, then

used his energy to start an improbable 18-0 spurt that Indiana used

to turn a 19-9 deficit into a 27-19 lead. Illinois went nearly 6

1/2 minutes without a point, and Brown's 3-pointer at the end of

the half managed to get the Illini within 28-24.

Killingsworth was 1-of-5 from the field, 1-of-3 from the

free-throw line and had an ailing back that needed more than a

rubdown.

"At halftime, I just prayed," he said.

The Hoosiers relied on him more in the second half.

Davis directed his players to start exploiting the middle,

especially after the Illini's interior players started to get into

foul trouble. This time, Killingsworth took advantage by hitting

short shots, drawing repeated fouls and creating havoc in the

middle for Illinois.

He looked like a completely different player.

"It seemed like the rim was that big," Killingsworth said,

extending his hands. "Stuff just started going in. I couldn't

believe some of the stuff that was going in."

Illinois was surprised, too.

They tried switching matching up, switching defenders, forcing

the ball out of Killingsworth's hands. But nothing worked.

During a 15-6 run that gave Indiana a 55-40 lead with 8:23 left,

Killingsworth scored 12 points.

"We focused on him a lot, but we're going to have to do a

better job than that from here on out," Augustine said.

Illinois answered with 12 straight points and when Randle

completed a three-point play with 4:52 left, the Illini were back

within 55-52.

Three times, the Illini got as close as two. When Jamar Smith

tipped in Dee Brown's errant 3 with 4.5 seconds left, Indiana's

lead was cut to 61-60.

But Robert Vaden hit 1-of-2 free throws with 3.6 seconds left,

Rich McBride's halfcourt heave was off the mark and the Indiana

fans streamed onto the court.

"Marco is a guy who is going to get his shot off against

anyone," Davis said. "He played great."
