Top 2017 NBA Draft prospect Markelle Fultz will reportedly only work out for the Boston Celtics.

The 19-year-old guard is considered the frontrunner to go No. 1 overall.

Fultz was in Boston over the past two days to undergo interviews, medical testing and an on-court workout.

Accompanied by Celtics president Danny Ainge, Fultz toured TD Garden on Tuesday.
