NBA draft prospects will get an opportunity to show teams what they can do at the 2018 NBA Draft Combine this week, but former Western Kentucky enrollee Mitchell Robinson and Boise State's Chandler Hutchison will not be in attendance.

According to Yahoo Sports' Shams Charania, both Robinson and Hutchison have withdrawn from the combine.

The reasoning behind the prospects' decisions are not known, as ESPN NBA draft analyst Jonathan Givony noted:

Per B.J. Rains of the Idaho Press-Tribune, Hutchison's withdrawal is not injury related.

The combine offers prospects a chance to put their skill sets on display as well as talk one-on-one with teams. Unless a player is a lock to go No. 1 overall, the event offers prospects an opportunity to improve their stock...or hurt it.

Mitchell was a 5-star recruit and a top-10 prospect coming out of high school, according to 247Sports. The 7'0", 222-pound center initially committed to Western Kentucky but wound up leaving the program before the season ever began. He left the Hilltoppers within a month of stepping on campus but returned shortly later, resulting in a suspension. He ultimately decided to bypass college to "pursue a professional career."

As a result, there is no film of Mitchell playing college ball—and any team interested will have to do their own digging to learn more about his path to the NBA.

Hutchison, on the other hand, used up his eligibility at Boise State. In four years as a Bronco, the 6'7", 197-pound guard steadily improved, averaging career-highs in scoring (20.0), assists (3.5) and rebounds (7.7) as a senior.

Bleacher Report's Jonathan Wasserman currently has Mitchell going No. 15 and Hutchison 22nd.
