After two days and three practices the Rockets are beginning to run out of centers. Dwight Howard remains the center of attention but his predecessor as the Rockets’ starter Omer Asik left the floor late in Sunday’s practice with a strained calf muscle. He is listed as day-to-day.

Greg Smith (strained right hip) is also day-to-day and Marcus Camby (plantar fasciitis) is out this week leaving Howard and rookie Jordan Henriquez available at the position. Guard/forward Francisco Garcia sat out Sunday to rest the sore groin muscle he tweaked at the Tournament of the Americas but had been practicing.
