The No. 3 seed Illinois Fighting Illini are moving on to the Elite Eight portion of the 2026 NCAA Tournament after pulling off a 65-55 win on Thursday against the No. 2 seed Houston Cougars in a Sweet 16 matchup at the Toyota Center in Houston.

Illinois basketball's suffocating defense played a big role in the Illini's success against Kelvin Sampson's squad.

The Cougars were held to only 34 percent shooting from the field. They had 13 more attempts from the field than Illinois, but failed to maximize those shots enough to avoid falling prey to the Fighting Illini.

Illinois is known more for its offense than what it does on the other side of the court, but it reminded everyone that it can also get things done when its scorers are not clicking.
