COLUMBUS, Ohio (AP) — No. 2 seed Tennessee is breathing easier after holding off what would have been a record rally by Iowa that forced the first overtime of this NCAA Tournament.

The Volunteers are on the way to the Sweet 16 after blowing a 25-point first-half lead. After ninth-seeded Iowa came back and tied the game with 20 seconds left in regulation, Tennessee pulled away for an 83-77 win in the extra period.

Our crew from Knoxville, Tennessee caught up with the proud players in the locker room after the victory.  You can watch their reaction in the video above.

The biggest comeback to victory in NCAA Tournament history was by BYU, which overcame a 25-point deficit to beat Iona in the First Four in 2012.

Jordan Bone hit a pair of foul shots late to seal it for the Vols.

Down 49-28 at the half, Iowa clawed back. The Hawkeyes scored nine of the first 11 points in the half and ripped off another 17-2 run.

Admiral Schofield had 17 points in the first half and finished with 19 for Tennessee. Grant Williams also had 19.
