Trebek says he was chasing a burglar at his hotel in San Francisco at 2:30 a.m. Wednesday when his Achilles tendon suddenly snapped. Trebek says when he fell, he also injured his other leg.
Police say the suspect, identified as 56-year-old Lucinda Moyers, entered his room and stole cash, a bracelet that his mother gave him, and other items.
Lt. Troy Dangerfield with the San Francisco Police Department told the San Francisco Appeal website, the victims were sleeping when the robbery began, but one awoke and gave chase.
Dangerfield did not disclose Trebek's name.
Moyers stashed the items near an ice machine on the floor Trebek was staying on.
All items except the cash and bracelet were recovered.
Moyers was arrested and booked on felony burglary and possession of stolen property.
The San Francisco Appeal reports the incident took place at the San Francisco Marriott Marquis hotel.
Trebek was still able to fulfill his hosting duties at the National Geographic World Championship.
Trebek reassured the audience that despite the incident, he is OK.
He will have surgery on Friday and is expected to be in a cast for six weeks.
