Kansas forward Perry Ellis (34) catches a pass in the paint before Connecticut forward Shonn Miller (32) during the first half on Saturday, March 19, 2016 at Wells Fargo Arena in Des Moines.

Kansas University senior Perry Ellis, junior Wayne Selden Jr. and freshman Cheick Diallo have been invited to the 2016 NBA Combine, set for May 11-15 in Chicago.

It’s believed all three will compete in drills and 5-on-5 games at the Combine, which is used both to measure and test prospects, plus watch them compete in drills and scrimmages.

Junior Brannen Greene, who also has declared for the draft, did not net an invitation to the Combine.

“(I’m) disappointed for Brannen, but he’ll still have opportunities to get in camps and work out for teams,” KU coach Bill Self said Saturday. “(I’m) happy for those other guys. They deserve to be there. Now it’s up to them to go perform well there.”

Greene has hired agent Sam Goldfeder of Excel Sports Management. Ellis has contracted with Mark Bartelstein of Priority Sports and Management and Selden with Neal Rosenshein of Summit Sports Group.

Until Diallo signs with an agent, he has until May 25 to pull his name out of the draft and return to college. Self has said he definitely does not expect Diallo, who is listed as a first-round pick by draftexpress.com, to return.

Ron Baker of Wichita State was invited to the Combine, but Fred Van Vleet was not, according to the Wichita Eagle.
