Thomas DeCoud suffers head injury

GREEN BAY, Wis. -- Atlanta Falcons starting free safety Thomas DeCoud is out for the rest of Sunday's game against the Green Bay Packers after suffering a head injury.

DeCoud was injured in the first quarter while attempting to tackle Packers rookie running back Eddie Lacy. On the play, Lacy scored a 1-yard touchdown.

DeCoud remained on the ground for a few minutes then exited the field while escorted by members of the team's training staff.

With DeCoud out, the Falcons inserted rookie Zeke Motta at free safety alongside strong safety William Moore. Motta continues to wear a cast after breaking a finger on his right hand.
