Koo made his only extra-point try and field goal attempt in Sunday's 18-10 loss to the Steelers.
Koo kicked a 24-yard field goal on the Falcons' opening drive, then added the extra point on a Kyle Pitts touchdown late in the second quarter. Other than the kickoff to open the second half, the Georgia Southern product remained on the sideline for the remainder of the matchup. Next up for Koo and the Falcons is a Week 2 matchup on MNF against the Eagles.
