Despite being up 16-0 in the first half and leading by three points until the last minute of the tilt, the Cardinals lost their seventh game of the season after the 49ers scored the go-ahead touchdown with 31 seconds left.
"I'm used to winning," quarterback Kyler Murray said after the game, according to ESPN's Josh Weinfuss. "I've always won, and then being in situations like when you go up 16 or you're in position to win and you should win, it's disappointing."
Although Arizona won three consecutive games early in October, it has now dropped to 3-7-1 in 2019.
Against San Francisco, Murray completed 24 of 33 passes for 150 yards and two touchdowns. He also added 67 yards and a touchdown on the ground.
"I'm a competitor," the signal-caller said. "I love the game of football so every time I step on the field I'm going to do me. I'm going to go hard for the guys in the locker room. So, that's really all I can do. Leave it all on the field and we just came up short."
Murray finished his college career in Oklahoma with an 18-3 record before being selected first overall in the 2019 draft. He's completed 64% of his passes for 2,703 passing yards and 14 touchdowns against five interceptions through his first 11 professional games.
The Cardinals have their bye week ahead before facing the Los Angeles Rams in Week 13.
