Jimmy Garoppolo went 1-for-6 for zero yards and an interception on Monday night in his first game since suffering a season-ending knee injury last September.

The San Francisco 49ers quarterback finished the night with a 0.0 passer rating.

"Obviously [I'm] a little frustrated," Garoppolo said.. "But it's the NFL, unfortunately we don't get to play the whole game. ... You wish you could be out there for more so you could bounce back. ... It is what it is. It's the preseason right now, so you just gotta take it in stride."

The 49ers signed Garoppolo to a five-year, $137 million contract last year. After a promising start to this season, he product tore his ACL in a Week 3 game against the Kansas City Chiefs.
