Former Duke star Cam Reddish will undergo surgery on a nagging core muscle injury just three weeks before the 2019 NBA Draft. 

According to The Athletic, which cited unidentified sources, Reddish is expected to need six weeks to recover. The injury carried over from his lone season at Duke, and he will have the "minor procedure" so that he can fully heal. 

Reddish went to Duke with high expectations, but he underwhelmed as a freshman. He averaged 13.5 points yet disappeared for long stretches and shot just 33.3% from 3-point range. Reddish helped Duke win the ACC Tournament, but the Blue Devils were eliminated in the Elite 8 of this season's NCAA Tournament by Michigan State.

Many have projected the 6-foot-8 forward to be a top-10 pick in the draft, and he likely will be the third Duke star to go off the board behind Zion Williamson and RJ Barrett. The injury isn't expected to have an impact on his draft stock. 

The draft is scheduled to start June 20 at Barclays Center in Brooklyn.
