SANTA CLARA, Calif. – The defense wilted in the heat, the offense couldn’t finish drives or protect the ball and the San Francisco 49ers frustratingly blew another late lead to a division opponent. Brock Purdy threw two interceptions in the second half, Jordan Mason lost a fumble in the red zone and San Francisco allowed Kyler Murray and the Arizona Cardinals to drive for two scores in the fourth quarter in a 24-23 loss that was eerily seemed familiar in a loss two weeks ago against the Los Angeles Rams.
