After Sunday's defeat at Miami, Howard was unable to walk due to a cyst on his left ankle that had been a bother for two and a half weeks, resulting in a DNP on Monday. He subsequently had the cyst removed and fluid drained, but another absence is expected Thursday. As long as he's sidelined, Omer Asik will take on center in the starting five.

Assuming the medical problem goes away in a few days with no long term effects, this seems to help the team towards the playoffs in two significant areas. First - Asik gets heavy minutes, getting back in form and sync with the other players. And... Howard gets some rest days which could be crucial a month from now.
