Ivan Rabb has narrowed his list of schools to Arizona, California, Kansas, Kentucky and UCLA.

Rabb is one of the top recruits in the class of 2015 and attends Bishop O'Dowd in Oakland.

Josh Sharma has given Stanford a commitment for the 2015 class.

Sharma is Stanford's third four-star recruit and is a seven-footer, who is ranked No. 83 in the country.

“Josh is still a few years away from being a major contributor in the Pac-12, but he’s developed nicely over the last 12 months and has great natural size,” NBCSports.com recruiting analyst Scott Phillips said. “Once he adds strength, he should be able to score in the post and rebound and defend his area.”

Henry Ellenson, ranked No. 4 in the ESPN 100, has committed to Marquette over finalists Michigan State and Kentucky, he told ESPN.

Ellenson will join brother Wally on the Golden Eagles' roster and will give coach Steve Wojciechowski his first five-star recruit since taking over the program last April.

"I felt Marquette was a place where I could make an immediate impact," he said. "I feel that I will have an opportunity to play multiple positions and show my versatility. Also, I was the most comfortable with the coaching staff and a chance to play with my brother was something that was always big to me."

Brandon Miller is taking an indefinite leave of absence from his position as head coach of Butler for medical reasons.

There are no details in regards to Miller's condition.

Miller replaced Brad Stevens as head coach of Butler in 2013.

The school announced that Chris Holtmann, who guided Gardner-Webb to a school-record 21 wins before joining the Bulldogs' staff last season, would be the interim head coach in Miller's absence.
