Box on back of Canadian women's soccer players.

During the Canada vs USA friendly women's soccer match, many of the Canadian players had a single rectangular shaped protrusion located high between the shoulder blades and under the jersey. What might this be?

Maybe it's a GPS to track their movement/speed throughout the game. Football (AFL) players wear them here in Australia.

Makes sense. It looks terribly uncomfortable though.

Player #4 on left, in red.

Player in red and goalie in light blue.

What you are seeing on their back is a suite of sensors in a rectangular package that fits between their shoulder blades. It is held in place under their jerseys by a rear pocket that is part of a specially designed sports bra. The sensors include GPS location, heart-rate monitor, gyroscope, and accelerometer.
