The Houston Dynamo and Chicago Fire were forced to end their MLS encounter early due to lightning and heavy rain.
The teams settled for a 1-1 draw after 66 minutes of play, having already suffered a 70-minute delay in the first half.
Will Bruin opened the scoring for Houston in the 24th minute with a near-post shot past Sean Johnson.
Logan Pause equalised for Houston seven minutes when Pavel Pardo's driven free-kick deflected off his head as he ducked to avoid it.
The score stayed level until the match was later abandoned.
