Jok flashed a big grin as he jogged back on defense and the Hawkeyes were up 53-38.When Jok wasn’t scoring, he was providing.Moments later he missed a jumper and the ball bounced away from the rim with Illinois’ Malcolm Hill close behind it, scrambling for the rebound.But Jok, laying on his back at the top of the key, found himself with the ball.

But the Illini could get no closer.Hill finished with 14 points and eight rebounds.Finke returned to the lineup after missing the Rutgers game with a bruised knee he suffered against Wisconsin.
