Williams (calf) will undergo an MRI on Saturday, ESPNNewYork.com reports.

Analysis:

Williams left Friday's game against the Cavs in the second quarter and did not return. The preliminary diagnosis is a right calf strain, but the Nets have ordered an MRI to get a better idea of the full extent of the injury. Consider Williams day-to-day and questionable to play Sunday against Detroit until the results of his exam are made public.
