Kicker Younghoe Koo has reportedly signed with the New York Giants following his release by the Atlanta Falcons, NFL Network's Ian Rapoport and Mike Garafolo reported Tuesday. Koo has not played since he missed a potential game-tying field goal for the Falcons in a Week 1 loss to the Tampa Bay Buccaneers. The signing comes after Giants kicker Graham Gano suffered a groin injury during warmups for the team's Week 3 game against the Kansas City Chiefs on Sunday. The Giants have turned to six different kickers over the last three seasons amid Gano's injury absences. He ultimately won the job but made his only appearance of the season in the Week 1 game against the Bucs.
