The Cardinals have released Grice.
Drafted in the sixth round of the 2014 NFL Draft by the Chargers, Grice ultimately latched on with Arizona for the 2014 season and logged 15 carries for 41 yards and a score across 10 games. However, throughout the 2015 campaign, he only spent time on the Cardinals' practice squad and never appeared in a game. Effectively, this move simply casts Grice into the free-agent market, and won't have any affect on Arizona's salary cap situation, as only their 51 largest contracts matter in that capacity right now, but it does open a roster spot.
