Garoppolo started Sunday after a two-game absence because of the injury he suffered in a Week 2 win against the New York Jets. But he, along with the rest of the Niners, struggled mightily as the Dolphins took a 30-7 lead into halftime. Coach Kyle Shanahan decided to turn to backup C.J. Beathard to start the third quarter.
According to the Fox broadcast, Shanahan said at halftime he was “worried” about Garoppolo and decided to go with Beathard because he “wants to protect” Garoppolo. Garoppolo was under pressure for much of the first half as the Dolphins sacked him three times and had four quarterback hits. He threw a pair of second-quarter interceptions as he struggled to get comfortable in the pocket.
In his two quarters, Garoppolo was 7-of-17 for 77 yards with no touchdowns and the two interceptions for a passer rating of 15.7.
After that performance, Shanahan promoted Beathard to the No. 2 quarterback spot this week with Garoppolo reclaiming his starting job.
On the Niners’ first possession of the second half against Miami, Beathard led a touchdown drive, hitting receiver Kendrick Bourne for a 19-yard score.
