Geiger was the referee for Atlanta United’s game against Sporting KC on May 9 at Mercedes-Benz Stadium. Atlanta United lost 2-0. Geiger correctly issued a red card to goalkeeper Brad Guzan for the denial of a goal-scoring opportunity in the 34th minute. He also controversially disallowed a Josef Martinez goal for offside, though the ball came off a Sporting KC defender who attempted a play on a pass from an Atlanta United player to Martinez.
Geiger became a part of the story 11 days later when Atlanta United hosted New York Red Bulls. Working as the VAR, Geiger recommended a review of a Martinez goal. The goal was disallowed. The score would have given Atlanta United a 2-0 lead. Red Bulls went on to win 3-1.
For the season, Geiger has worked as the referee in 13 MLS games. He has awarded 289 fouls, 34 yellow cards and four red cards. Three Atlanta United players, Eric Remedi, Hector Villalba and Martinez received yellow cards in the first leg of the series. If they receive another on Sunday, and Atlanta United advances, they will be forced to miss the first game of the conference final.
