About the Fire: After tying the score on a goal by home-grown midfielder Joey Calistri in the 81st minute, Chicago surrendered the game-winner in the 89th minute during Saturday's loss in Colorado. . . . Designated player and forward Gilberto will not make the trip to Philadelphia and will miss his third straight game. He is still training in Chicago but appears to be at a contract impasse with the team. . . . Forward Kennedy Igboananike has a team-high four goals, including one game-winner. . . . Forward-midfielder David Accam has three goals and two assists in just six games. He has played the full 90 minutes in each of the last two games.

About the Union: The Union had their club record- tying eight game unbeaten streak snapped in Saturday's loss to NYC FC at Yankee Stadium. . . . C. J. Sapong, whose five goals are tied with Chris Pontius for the team lead, missed his first MLS game Saturday with an ankle injury. Sapong is again questionable. If he doesn't go, rookie Fabian Herbers will likely get his second consecutive start. . . . Rookie defender Josh Yaro, out since March 25th with a right shoulder injury, has been cleared to play and could see action Wednesday.
