Terrell (head) is being evaluated for a possible head injury, according to Tori McElhaney of the Falcons' official site.
EDGE Analysis
Terrell is being evaluated, but no further information has been given about the injury -- though head injuries are something that causes concern league-wide, and the Falcons might be cautious upon Terrell's return. If he can't go, then T.J. Green or Darren Hall would be in line to see more snaps in the secondary.
