Smart (illness) will not play in Friday's preseason game against the Knicks, Jay King of MassLive.com reports.

EDGE Analysis

This is the second game in a row he'll miss, as he's been dealing with an illness over the past week. The Celtics are likely just being cautious with their young guard and there's no reason to think Smart won't be ready to go come Monday's preseason tilt with the Nets.
