Watch: North Carolina coach Roy Williams collapses during timeout

North Carolina coach Roy Williams appeared to collapse on the sideline during the Tar Heels’ game against Boston College on Tuesday.
During a TV timeout in the second half, Williams was speaking to his team when he fell to his backside. Williams was then helped to the locker room.
Williams has experienced issues with dizziness in the last few seasons, according to The Charlotte Observer’s Andrew Carter.
A North Carolina spokesman told the media Williams was “doing okay” and was taken to the locker room because he was experiencing dizziness.
Roy Williams in recent years has told us that he has been tested for assortment of conditions that could cause these dizzy spells ...

... Those tests, he has told us, haven't led to anything conclusive. Has dealt with them for a while. Don't think he's ever left a game, tho
