Denver Nuggets center Marcus Camby was inactive for Friday night's game against the Western Conference-leading Dallas Mavericks because of a lower back strain.

Camby's back tightened overnight, the team said. He is listed as day to day.

Camby is averaging 14.9 points, 12.4 rebounds and 3.1 blocks. He has missed 20 games this season because of injury -- 15 with a broken right pinkie.
