Just days after Rick Crawford's terrifying collapse after being elbowed during the opening tip of La Salle-Vanderbilt, another college basketball referee has had to leave the game due to jump ball-related injury.

Referee David Hall is the victim this time, injured on the tip to open overtime tonight between Wichita State and Utah. It looks like Hall will be OK—fortunately, Crawford was—but this is an odd and scary trend.
