Monday night in San Francisco, the Los Angeles Rams were shut out by a 49ers team that last season ranked 29th in the NFL on defense. They mustered just 185 total yards in the 28-0 loss, converting just three of 15 third downs.

Keenum completed just 48.6 percent of his 35 passes for 130 yards. He threw two interceptions and was sacked twice, finishing with a 34.
