SAN ANTONIO, Texas (AP) — A tiger at the San Antonio Zoo attacked a keeper Saturday, critically injuring him, the zoo said.

Rescue workers wheel a zookeeper injured by a tiger to a medical helicopter Saturday in San Antonio, Texas.

The zookeeper, a man in his 20s, was attacked about 2:30 p.m. out of view of the public, said zoo spokeswoman Dawn Campos. The man, who specializes in large cats, was flown to a hospital and was in critical condition, a hospital spokeswoman said.

Campos said she did not know the extent of the zookeeper’s injuries but said: "He was very, very fortunate. He’s going to be fine."

The male Sumatran tiger is 4 or 5 years old, Campos said.

The zoo was closed after the attack and was expected to reopen Sunday, Campos said.
