Additionally, midfielder Kevin Kratz suffered a setback in his return from a calf injury. Kratz has one appearance this season.

“He has to start all over again,” de Boer told reporters. “It’s not looking good.”

De Boer said the starting lineup for Tuesday’s game will be a mix of regulars and reserves. The midfield in the game against Charleston was composed of Andrew Carleton, Pity Martinez and Dion Pereira.

Striker Romario Williams, who scored a goal and later appeared to sustain a groin injury in the win against Charleston, did train Monday.

Columbus will be without several key players, including striker Gyasi Zardes, midfielder Wil Trapp and goalkeeper Zack Steffen, who are with the U.S. national team competing in the Gold Cup.
