Reid (head) has been ruled out for Tuesday's game against Denver, Tim MacMahon of ESPN.com reports.
Reid will join Karl-Anthony Towns (knee) on the sideline while Rudy Gobert (ribs) remains questionable, leaving Minnesota compromised in the frontcourt. Luka Garza will likely remain in a fringe rotation role regardless of Gobert's status, while Kyle Anderson appears locked into a 30-plus minute workload and could see some run as a small-ball center if Gobert can't go.
