Wilcox sustained the injury last Wednesday night in Chicago against the Bulls while bracing his fall after taking a charge.
"Chris [Wilcox] is out; he's out for a while," Rivers said. "The report I got was three to four weeks. He'll be out."Varnado is 6'9" and was the 41st overall pick in 2010 by the Heat but never played a for them. He isn't the tallest center but is able to block shots because of his athleticism and long wing-span. He currently holds the NCAA Division 1 record for most blocked shots in a season.
