In the Falcons' October 9, 2005 game against the New England Patriots, they had the ball on New England's 41 yard line with six seconds remaining in the first half. Since regular placekicker Todd Peterson's range was insufficient to attempt a field goal from that distance, Falcons head coach Jim Mora turned to Koenen. Koenen actually attempted the kick, the first field goal attempt in his pro career, twice. Prior to the initial snap, Patriots linebacker Mike Vrabel called a timeout. Koenen heard the referee's whistle but still kicked the field goal. It landed right of the goalpost. A few moments later, Koenen attempted the kick again, and this time made an official 58 yard field goal. It was the longest field goal of Koenen's career at any level, tied for the ninth longest in NFL history (as well as the single longest in the 2005 season), and was the third longest in history by an undrafted kicker.
