The USOC will meet tomorrow on Boston’s shaky bid for the 2024 Summer Olympics, where one board member told the Herald she won’t be surprised if the 17-day, $4.6 billion plan comes up for a fateful vote.

“We need to know how (Boston) is doing and if the people of the city are interested in hosting the games,” said Anita L. DeFrantz, a member of both the United States Olympic Committee and the International Olympic Committee.

“We need to get a report. I need to know,” DeFrantz told the Herald yesterday, voicing doubt about support for the games in the Hub.

DeFrantz, en route to an IOC meeting in Kuala Lumpur, declined to comment on a report from an Olympic writer in Malaysia that a vote is being called on Boston’s bid. But, she added, “I’ve learned to not be surprised by much” if it happens.

“We selected them and we’ll see what’s up,” she said.

As for speculation Los Angeles is poised to step in if the USOC backs away from Boston, DeFrantz said “L.A. is perpetually ready. It can host with only two years’ notice.”

The infrastructure is in place, she added of the City of Angels, and she pointed out the Special Olympics is being held in L.A. right now. The city also hosted the 1932 and 1984 Summer Games.

The Herald was told by another official that Boston’s bid is on the agenda for tomorrow’s USOC teleconference with its 16 members. A new member, Bob Wood of Colorado, is also being welcomed to the panel. Wood could not be reached for a comment.

Gov. Charlie Baker said he will also speak to the USOC tomorrow, but he repeated yesterday he will not make a decision about backing or not backing the games without the results of a state-commissioned independent study expected out next month.

“I said I would call into the meeting and give them an update on where we are,” Baker said during a stop in Mattapan. “That study’s going to be critical to our decision.”

Baker said the USOC has not been in contact with his office about what he’s expected to reveal tomorrow.

The IOC has set Sept. 15 as the day cities must commit to bidding for the 2024 Summer Games, with a final decision not coming until 2017 at its meeting in Lima, Peru.

Budapest, Hamburg, Paris and Rome — and possibly Toronto — are all also said to be vying to host the 2024 Summer Games.

Boston 2024, the organization headed by Celtics boss Steve Pagliuca, who is also managing partner of Bain Capital, did not comment last night on the USOC meeting.

Mayor Martin J. Walsh, also a backer of the city’s Olympic bid, declined to comment on the report of a possible USOC vote.
