Arkansas freshman Nick Smith Jr., considered the best NBA prospect in college basketball, is out indefinitely for "right knee management," per the school.
Smith missed the first six games of the season with the same issue, with the school calling it precautionary at the time.
The 6-foot-5 guard made his season debut against Troy on Nov. 28, playing just six minutes. Coach Eric Musselman inserted Smith into the starting lineup the next game, and Smith proceeded to average 19.7 points and 3.0 assists over his next three fully healthy games.
Smith started and played 20 minutes in Arkansas' win over Bradley on Saturday, finishing with five points on 1-for-8 shooting.
