The 49ers called Sunday's loss to the Rams -- in which they blew an early lead and made miscues on several key plays -- "unacceptable."

Their pre-game odds weren’t great but their chances of winning late in the fourth quarter were even worse. According to ESPN, the Rams only had a 4.5% chance of beating the 49ers with 4:57 left in the game after Jordan Mason rushed 4 yards for a first down to Los Angeles’ 42-yard line.

Joshua Karty hit a 37-yard field goal with 2 seconds to play, and the Los Angeles Rams staged a spectacular late rally for a 27-24 victory over the San Francisco 49ers
