Alfonso Plummer sank two free throws with 12 seconds left Friday night as fourth-seeded Illinois escaped 13th-seeded Chattanooga's upset bid 54-53 in a first-round NCAA Tournament South Region game in Pittsburgh.

The Mocs (27-8) had two chances to win on their final possession, but leading scorer Malachi Smith had his first shot blocked by Coleman Hawkins and then missed a 17-footer as time expired.

Kofi Cockburn scored 17 points and grabbed 13 rebounds for the Fighting Illini (23-9), who will face fifth-seeded Houston, which defeated 12th-seeded UAB 82-68 on Friday, in the second round on Sunday. Plummer finished with 15 points and Hawkins added 10 points and eight rebounds.

Smith scored 12 points and pulled down eight rebounds for Chattanooga, but he made only 4 of 20 shots from the field and missed his last eight attempts.

The Mocs' second-leading scorer, David Jean-Baptiste, who hit a 30-footer at the final horn to win the Southern Conference title and send Chattanooga to the NCAA tourney, connected on just 2 of 11 shots and scored four points.

Chattanooga led for all but 1:25 of the game, earning a 43-41 edge on the boards and holding Illinois to 38.8 percent shooting from the field.

"They just knocked us right in the mouth the first six minutes of the game and took it to us," Illinois coach Brad Underwood said. "Kicked our butt. They were much more ready to play than we were from an energy and execution standpoint."

The Mocs opened early leads of 14-3 and 20-6 despite finding foul trouble inside early. Silvio De Sousa was whistled for two quick fouls and Josh Ayeni also committed two early fouls while trying to guard Cockburn.

But Illinois simply couldn't make shots -- either from the field or the line. The Illini enjoyed a significant advantage in free-throw attempts but couldn't make it matter, hitting only 9 of 17 before halftime. Cockburn, who was fouled on a steady basis, converted just 5 of 10 free throws in the first half.

The Illini didn't reach double figures until Omar Payne sank a layup at the 7:44 mark to make it 20-10. They found a little rhythm later in the half, drawing within 31-29 on a Cockburn dunk in the last minute before Smith canned a layup to put the Mocs ahead 33-29 at intermission.

The Mocs were up 40-29 early in the second half, but a 10-0 Illinois run wiped out most of the deficit.
