Treggs will have an MRI performed on his knee Sunday, Cam Inman of Bay Area News Group reports.
Analysis:
Treggs suffered the injury during Saturday's preseason matchup with the Broncos. It's being listed as an MCL injury, but the impending MRI should reveal whether it's just a sprain or a full-blown tear. Treggs was battling for a roster spot at wide receiver, so this is a tough blow for the 22-year-old rookie out of California. We should know more about a potential return to the field shortly.
