Kaman (illness) is out for Thursday's game against the Celtics, Casey Holdahl of the Portland Trail Blazers reports.

Kaman has been dealing with an upper respiratory illness that has kept him sidelined since Monday. The last time he played came against the Pelicans on Mar. 18 where he logged one minute of playing time. With Kaman out, look for Noah Vonleh, Mason Plumlee, and Ed Davis to contribute playing time on par with their current outputs.
