The Broncos got their hands on all four of Garoppolo’s first four passes Monday night.
They intercepted one, dropped a pick-six and had pass breakups on the other two.
Garoppolo’s third drive wasn’t much better as he completed 1-of-2 passes — a screen pass to Matt Breida that went for no gain.
So Garoppolo’s stat line read: 1 for 6 for no yards with an interception in 10 snaps over three series. It was that ugly.
C.J. Beathard replaced Garoppolo with 1:19 remaining in the first quarter.
General Manager John Lynch said Saturday that Garoppolo’s return from his knee injury has been “flawless.” But Garoppolo showed Monday he still has a lot of work to do in the next three weeks, which has to concern the 49ers.
