Jarnell Stokes dominated inside as Tennessee finally caught up in the closing minutes of regulation, and then opened overtime with a three-point play that got the Volunteers headed to a 78-65 victory over Iowa on Wednesday night in the NCAA's First Four.
The Volunteers' late comeback sent them Raleigh, N.C., where they'll play sixth-seeded Massachusetts on Friday in the Midwest Regional.
Tennessee (22-12) didn't lead until Antonio Barton's 3-pointer put the Vols up 59-57 with 3:05 left regulation.
There were five lead changes before the Vols' Jordan McRae missed a jumper missed at the buzzer, leaving it tied at 64.
Stokes' three-point play was the key moment in his 18-point, 13-rebound performance. Iowa (21-13) managed only one free throw in overtime, ending a hectic and stressful day for coach Fran McCaffery.
McCaffery started the day in Iowa with his teenage son Patrick, who had surgery to remove a thyroid tumor.
