San Francisco abandoned its bid to host the 2016 Summer Olympics after plans for a new bayfront stadium collapsed when the San Francisco 49ers football team said they intended to move to nearby Silicon Valley.
Los Angeles and Chicago are now the remaining US candidates to hold the games following Monday's announcement by the San Francisco 2016 Bid Committee.
John York, owner of the 49ers, told city officials last week he was breaking off negotiations for a new stadium at Candlestick Point and was considering a move to Santa Clara.
Scott Givens, managing director and chief executive officer of the bid committee, said the 49ers' decision created a "perceptual gap" that hurt the city's reputation in the eyes of the Olympic committee.
"The damage has been done and the damage can't be pulled back," he said.
