Patrick Peterson not on the field

ATLANTA -- North Carolina burned LSU with a 97-yard touchdown pass to pull within 30-17, but LSU's Patrick Peterson wasn't on the field.

In fact, Peterson hasn't been in the game at cornerback a couple of different times in the second half.

He left the game early at the end of the first half and went to the locker room to have some IV fluids administered, according to LSU officials.

It's been a busy night for Peterson in the return game. In fact, even though he wasn't on the field for the Tar Heels' long touchdown pass, he was back deep on the next play when North Carolina kicked off.
