Katie Ledecky withdrew from the 200-meter freestyle preliminaries and the 1,500 free final Tuesday at the world swimming championships in South Korea because of illness.

Her coach, Greg Meehan, said doctors were assessing Ledecky, but had no official diagnosis.

“She woke up this morning and she’s not feeling well at all,” he said. “I’m hopeful that we see her racing again this week.”

The eight-day meet ends Sunday.

Shortly after Meehan spoke to reporters came word that Ledecky was out of the evening’s 1,500 free final.

Ledecky was the fastest qualifier for the grueling event in 15 minutes, 48.90 seconds – 2.68 seconds faster than the next quickest swimmer. But she hasn’t been in the pool since Monday’s prelims.

U.S. national team managing director Lindsay Mintenko said Ledecky hasn’t been feeling well since she arrived in Gwangju on July 17.

British swimmer Adam Peaty became the first man to win a third 100-meter breaststroke title at the world championships, claiming the title in 57.14 seconds Monday night.

Canada’s Margaret MacNeil, a 19-year-old competing in her biggest international meet so far, upset Sarah Sjostrom in the women’s 100 breast, an event the Swede had won four times.

The deal was to be presented to the City Council on Monday and then put to a vote. Calgary citizens would then have a week to voice their opinion before a council vote next week to ratify the deal.

The cost of the event center is $550 million to $600 million. It is to have a seating capacity of about 20,000 for sports.

The Pittsburgh Penguins and forward Zach Aston-Reese avoided arbitration, agreeing to a two-year deal worth $1 million annually. The sides came together minutes before heading to arbitration.
