A keeper at Tiger Haven was injured by one of the big cats on Friday.
Roane County E-911 received a call at 10:21 a.m. about a tiger biting a woman on the leg.
The Tennessee Wildlife Resources Agency concluded it was a scratch, not a bite.
Agency spokesman Don King said he was briefed on the incident by TWRA captive wildlife coordinator Walter Cook.
According to King, the keeper was feeding the tiger. She turned around, and the big cat swiped her on the back of the leg, King said.
