GREENVILLE, S.C. -- North Carolina saw its season flash before its collective eyes, and the Tar Heels did everything they could to make sure they would play another day.

"We finally stopped them a couple times and made plays," North Carolina forward Justin Jackson said. "Our season was on the line. ... It was just believing. Believing we can win."
Isaiah Hicks scored six of the points in the winning spurt, sending North Carolina to the Sweet 16 for the 22nd time since 1985. The Tar Heels eliminated the Razorbacks in the second round for the second time in three seasons and third time overall (also in 2008).

Arkansas went ahead 47-46 with 13:05 remaining, wiping out what had been a 17-point hole and going up by four.
"We started taking bad shots," Hicks said. "They took advantage of it. The last three minutes we picked it up."

North Carolina scored the rest of the points. Meeks converted on a tip-in as the shot clock was about to expire for a three-point led.
"We had never won a game like this this year," Jackson said. "We have a bunch of different players who and make plays and that showed."
Arkansas' Moses Kingsley missed two foul shots with 25.2 seconds to play. At the other end, Berry missed the front end of a 1-and-1 before Beard's potential 3 bounced high off the rim.
