An MRI performed on Suns center Robin Lopez revealed a moderate sprain of the medial collateral ligament (MCL) and posterior cruciate ligament (PCL) in his left knee.  Lopez is expected to be out several weeks.  Lopez will travel with the team when it departs on its four-game road trip Tuesday.

Lopez has started all nine games for the Suns in 2010-11, posting averages of 5.3 points and 4.3 rebounds in 17.8 minutes.
