The New York Giants are adding former Atlanta Falcons kicker Younghoe Koo to their practice squad. Giants kicker Graham Gano suffered a groin injury on Sunday in pregame warmups prior to their 22-9 loss to the Kansas City Chiefs. The Falcons released Koo, 31, on Sept. 19 after a rough start to the season. In the season opener, a 23-20 loss to the Tampa Bay Buccaneers, Koo missed a 44-yard try in the closing seconds. Koo joined the Falcons in 2019 and went on to become one of the NFL’s most reliable kickers.
