Members of 44 various groups snagged more than 3,000 tickets -- about 25 percent of the total allotted for students -- during Monday's block seating distribution at the Smith Center.
Director of Ticket Operations Clint Gwaltney said that students have been turned away from block seating in the past but that it was "not very common."
"Far more were turned away in this game than others," he said. "More groups applied, but we filled only a third of the applications."
Gwaltney said that about the same number of blocks were given out for the Texas game last month but that no students were turned away.
Groups were selected for block seating randomly, Gwaltney said.
"They're basically pulled out of a hat," he said. "Random selection is the best we can do."
Carolina Athletic Association President Kris Willett said it was the only way to pick which students get blocks.
"It is unfortunate they had to be turned away, but they have another chance (this) morning," she said.
Block seating appealed to students who wished to sit with large groups and wanted avoid waiting in this morning's ticket distribution line. Distribution for the remaining student tickets begins at 8 a.m. today. At 10 p.m. Monday students were already camping out at the ticket office in line.
