Ariza (foot) has been ruled out for the Rockets' upcoming three-game road trip. Ariza originally suffered the injury during Monday's tilt with the Grizzlies and is now set to miss the next three games with what's being listed as a left midfoot sprain. He's expected to be re-evaluated once back in Houston, which should give us a better indication on the severity of it, as well as if Ariza could be in danger of missing more time.
