Representatives from adidas headquarters in Portland, Oregon and Germany were at Rapids training today, having brought a new adidas ball for the team to train with for the day.
The Colorado Rapids, along with the Portland Timbers and Houston Dynamo, are the three MLS sides from which adidas is gathering feedback on the ball. They told us that they've also already tested the ball with players at AC Milan, Chelsea, and Ajax, and said they'll be visiting more teams around the world in the coming months.
This is not uncommon. Last summer, the Rapids tested the current adidas Prime match balls over a week's time.
That said, there's not much more info that can be public on the ball the team used today. But we are thankful that these reps at least allowed us to inform fans that this occured, even if we can't provide a better picture of the ball than this.
