Seattle Seahawks center Max Unger and defensive end Red Bryant are both going through concussion protocols after being injured on Sunday against Tampa Bay.
Coach Pete Carroll said Monday that the Seahawks are unsure if either will be ready for Sunday's game at Atlanta. Carroll said Bryant's concussion wasn't fully realized until Monday.
Carroll added that offensive tackles Breno Giacomini (knee) and Russell Okung (toe) are expected to practice this week. Okung is not eligible to come off injured reserve until next week and Carroll said it's unlikely Giacomini will be ready to play against the Falcons.
Wide receiver Percy Harvin's return from hip surgery remains a daily evaluation, but Carroll said the team is "not counting on," Harvin playing this week.
