With pressure mounting on Boston’s potential bid for the 2024 Summer Olympics, sources close to the situation continue to insist there have been no official discussions about making Los Angeles a last-minute replacement.

The sources -- who asked not to be identified because they are not authorized to speak publicly -- said that despite persistent speculation, the U.S. Olympic Committee has never spoken to Los Angeles officials about a Plan B scenario.

Boston’s campaign has suffered from consistently low support among residents and did not get any help from comments made by a USOC member speaking before the Boston City Council this week.

Angela Ruggiero said there was “no guarantee” the USOC would stick with Boston when the deadline for bid applications comes around this fall.


The USOC quickly backtracked, saying it remained fully committed to its selection.

Boston won the right to be the sole American bidder last fall, barely defeating a bid by two-time host Los Angeles.
