The 6-foot-11 Monroe missed Wednesday's game against New York with a sprained left ankle. Detroit remains without coach Lawrence Frank, who is missing his second straight game because of a personal matter.
Monroe is averaging 16.1 points and 9.5 rebounds on the season. Detroit, which is still without rookie big man Andre Drummond, has lost six of seven.
Drummond has a stress fracture in his back.
Assistant coach Brian Hill is filling in for Frank.
