Sick Larry Brown not on SMU bench after halftime

Brown leaves game due to vertigo (0:45)

SMU associate head coach Tim Jankovich explains why coach Larry Brown left before the second half of the Mustangs' game against UCF. (0:45)

DALLAS -- Hall of Fame coach Larry Brown was absent from the bench during the second half of No. 15 SMU's 88-73 win over UCF on Sunday.

School officials said the 75-year-old Brown wasn't feeling well and was dealing with symptoms of vertigo. Brown has had similar issues in the past.

Brown told ESPN's Andy Katz that the vertigo was related to getting no sleep as a result of the situation with junior guard Keith Frazier taking leave from the team for personal reasons, combined with being dehydrated.

"I'll be fine," he said.

Associate head coach Tim Jankovich directed the team in the second half against UCF.

The Mustangs, one of two undefeated Division I teams, were playing the 15th of their 30 games this season.

SMU is banned from postseason play because of NCAA sanctions handed down the past fall. Those include a nine-game suspension of Brown to the start of the season. Jankovich also served as head coach during that span.
