Roy Williams helped off court during UNC game Posted Mar 2, 2019 Roy Williams exited No. 5 North Carolina's matchup at Clemson on Saturday after falling to a knee late in the first half due to what the school said was another bout with vertigo. UNC officials said that Williams was feeling better, but he did not return to the game -- an 81-79 UNC win. Williams suffered a similar-looking incident at Boston College in 2016. (ESPN.com)
