"Wheel of Fortune" host Pat Sajak is recovering from emergency surgery.
The show tweeted Friday that Sajak underwent surgery for a blocked intestine, causing Thursday's taping schedule to be canceled. Sajak, who turned 73 last month, is said to be resting comfortably.
Taping resumed Friday with co-star Vanna White filling in as host. It is not clear when the episodes will air.
"Wheel of Fortune" airs weeknights at 7 p.m. on Channel 13.
