Jimmy Garoppolo's Week 2 appearance as a saviour was overshadowed by the 49ers' 11–10 loss to the Denver Broncos at Empower Field at Mile High on Sunday night.
Garoppolo appeared to be the quarterback who did not practise during OTAs and training camp, with the exception of the 49ers' lone touchdown drive on their second possession of the game.
The most severe mistake was when Garoppolo failed to recognise his surroundings during the second drive of the third quarter, which resulted in a safety.
Garoppolo tried to extend the play on second down while being pressed by Broncos defensive tackle Mike Purcell.
Garoppolo tossed the ball to the left sideline while stepping back and out of bounds with both feet.
The safer of the two play-related outcomes was the play being whistled dead for safety reasons.
Bradley Chubb successfully intercepted and returned a Garoppolo throw meant for Jeff Wilson, giving the Broncos the lead.
Kyle Shanahan, the coach, admitted responsibility for the poor play following the game.
Garoppolo acknowledged that the offence, including on the safety, struggled to get going after the 49ers' lone touchdown drive of the game early in the first quarter.
