Bertrand (concussion) won't play against the Cowboys on Sunday, D. Orlando Ledbetter of The Atlanta Journal-Constitution reports.
Bertrand was concussed in Sunday's win over Tampa Bay and hasn't cleared the NFL's five-step protocol. The linebacker logged 73 percent of the team's defensive snaps in Week 5 but has otherwise played primarily on special teams. Bertrand's absence Sunday could pave the way for Rashaan Evans, who was signed to the 53-player roster Friday, to see some work on defense immediately.
