SAN FRANCISCO -- Alex Trebek, host of the television game show "Jeopardy," was injured early Tuesday as he chased a burglar in his San Francisco hotel.

The longtime game show host appeared on crutches Wednesday to host the National Geographic World Championship at Google Inc.'s Mountain View headquarters.

"It happened at 2:30 a.m., chasing a burglar down the hallway of my San Francisco hotel, when my Achilles tendon ruptured and I then fell on carpet, bruising the other leg in process. Surgery on Friday," Trebek said, according to Patch.com. A spokeswoman at the Marriott Marquis confirmed the incident took place at that hotel.

San Francisco police officials confirmed a burglary at a San Francisco hotel early Tuesday, but would not identify Trebek, 71, as the victim. Lt. Troy Dangerfield said two people were asleep in a hotel room when "around 3 a.m., one of the victims awoke to notice someone in the room and then noticed the suspect leaving the hotel room."

Dangerfield said the victim was injured in the process of chasing the suspect. Hotel security apprehended the suspect, Lucinda Moyers, 56, of San Francisco, he said. Dangerfield said the victim identified the suspect.

Moyers, who was not an employee of the hotel, was booked on charges of burglary and receiving stolen property, Dangerfield said.

The victims' stolen items - purses and wallets - were found near an ice machine in the hotel, Dangerfield said. He said stolen cash was not immediately recovered.

Trebek fulfilled his hosting duties at the geography bee, which was hosted this year by Google.
