Devonta Freeman is in the NFL's concussion protocol after displaying symptoms on Sunday.
"After taking him inside yesterday where we thought he had heat related (issues), he reported that he had some concussion symptoms," Dan Quinn said, per the Atlanta Journal Constitution. "So, we put him in the protocol for that. He'll be out this week. He may start practicing as we, but we are going to rule him out now."
Freeman could miss the remainder of the preseason.
The Atlanta Falcons recently signed Freeman to a five-year, $41.25 million extension.
