Chalupny, 29, had an assist and drew the penalty that led to the Red Stars' third goal in a come-from-behind 3-1 victory over FC Kansas City on June 16.
The St. Louis native utilized her speed to beat FC Kansas City's defense down the left side before setting up Inka Grings for the game-tying goal with a pinpoint cross in the 29th minute. The assist was Chalupny's second of the season to go along with her three goals this campaign for the Red Stars.
Chalupny put her quick feet to use again in stoppage time when she went past FCKC's Nia Williams before being taken down by the defender. Red Stars defender Sonja Fuss stepped up and converted the ensuing spot kick to secure the 3-1 win.
The foul in the box was one of four suffered in the game by the former U.S. international, who leads the NWSL with 29 fouls suffered - 10 more than any other player in the league.
The Chicago Red Stars will return to action Wednesday, June 19 at 7:30 p.m. ET against the Western New York Flash at Benedictine University Sports Complex in Lisle, Ill.
