"The practice door swung open Monday and Grizzlies forward Zach Randolph emerged, dragging his leg because of a bruised right knee.

Today, Randolph hauls his injured knee to the doctor for magnetic resonance imaging that will determine the extent of his injury.

Randolph is believed to have a bruised medial collateral ligament, which usually is nothing serious. However, barring miraculous healing, the Grizzlies' power forward will sit out tonight's home game against the Sacramento Kings. "
