Wide receiver Kenny Britt suffered a shoulder injury that knocked him out of the Los Angeles Rams' 22-21 loss to the San Francisco 49ers on Saturday afternoon, according to ESPN.com's Alden Gonzalez.
It's unclear how severe Britt's injury is since the team hasn't announced an official diagnosis, but the Associated Press' Greg Beacham noted the veteran pass-catcher was "holding his right arm motionless and in obvious pain as he leaves the field."
Before he exited, Britt posted one catch for 15 yards and became the first Rams receiver to notch 1,000 yards in a season since Torry Holt did so in 2007, per the team's official Twitter account.
