Creighton spokesman Rob Anderson said in a text message Sunday night that X-rays showed no fractures or bone chips in the knee. The freshman injured his medial collateral ligament when he got tied up with a defender in Saturday’s 75-69 loss at Xavier. Zierden will undergo an MRI on Monday.
Zierden, who is averaging 3.3 points in 11 minutes per game, has played an increasing role the past month. He had season highs of 13 points and 24 minutes in a win over then-No. 6 Villanova on Feb. 16.
