The 49ers will not pick up their option on guard Joshua Garnett, according to NFL.com’s Tom Pelissero (on Twitter). This was expected – thanks to injuries, Garnett has not lived up to the expectations laid out for him when the Niners used a late first-round pick on him in 2016. 
Garnett missed all of 2017 after undergoing knee surgery and only saw action as a reserve in seven games last year. Given his underwhelming performance and injury history, the Niners were not about to trigger his $10.350MM option for 2020, which they would have been stuck with if he was unable to pass a physical heading into next year.
The Stanford product started in 11 of his 15 games as a rookie, but even then, his performance was underwhelming – Garnett racked up penalties and didn’t excel in run blocking or pass blocking. The good news is that the team says Garnett is finally healthy, so this year could be an opportunity for the 25-year-old to turn a corner and boost his value before hitting the open market.
