Coach Marc Trestman gave little clarity about the status of the Chicago Bears' injured players, a day after Pro Bowl receivers Alshon Jeffery and Brandon Marshall got banged up along with center Roberto Garza and left guard Matt Slauson.

The Bears suffered a surprising 23-20 overtime loss to Buffalo on Sunday.

Garza and Slauson exited with ankle injuries, leaving the Bears without two starters on the line. Jeffery spent most of the second half on the sideline with a hamstring injury and Marshall limited down the stretch after twisting his right ankle.

Trestman says the evaluations were "ongoing" for the next two days. Chicago plays at San Francisco on Sunday night.
