Miami Heat center Zydrunas Ilgauskas missed his second consecutive game because of a foot infection. Ilgauskas spent two days in the hospital before being released Monday. He was not on the bench for the game against the San Antonio Spurs at AmericanAirlines Arena. Heat coach Erik Spoelstra said there is no timetable on his return. He is doubtful for Wednesday's game against the Oklahoma City Thunder. "He is at home resting right now," Spoelstra said. "We'll have to wait and see [when he returns], until he gets back into gear." The injury occurred when Ilgauskas recently stepped on a nail. Spoelstra said the infection worsened because it wasn't treated immediately. He said it was something that got "progressively worse" in the past couple days.
