The running back is still in concussion protocol, but he was on the field with his pads and helmet on, catching passes from Cutler, NFL Network's Tom Pelissero reported. Ajayi is not cleared for game action, but having him on the practice field is a positive sign for the running back's progression.
Video evidence of the news:

Ajayi's progression back from concussion protocol is important as we grind toward the regular season. The bruising back was a top-five runner down the stretch last season, despite playing behind a porous offensive line. Ajayi enters 2017 as the focal point of Gase's offense.
A healthy Ajayi gives the Dolphins one of the most balanced offenses in the NFL. Tuesday's participation marks a step in him returning to full health.
