The NBA announced its full list of participants in this year's NBA Combine Tuesday, and joining freshman Josh Primo in Chicago will be seniors John Petty, Jr. and Herb Jones.

Sophomore guard Jaden Shackleford, who also declared for the NBA Draft in April, was not selected to join the pool of 69 players for the event. This should prompt his return to Alabama for the upcoming 2021-22 college basketball season, which he will have to determine before July 19.

Jones and Petty are expected to be second-round picks, according to many draft outlets, including NBADraft.net. In the site's official mock as of June 2, Jones was projected 46th-overall to the Toronto Raptors while Petty was projected 57-th overall to the Charlotte Hornets.

As for Primo, it seems all but certain now the 6'6" guard will remain in the 2021 NBA Draft pool. The Canadian prospect has turned eyes in the NBA scouting community and is projected in some circles to hear his name called in the first round of the draft, which will be held July 29 in Brooklyn, New York.

Primo was projected as high as 25th-overall to the Denver Nuggets in March according to Bleacher Reports's Jonathan Wasserman.

Primo hired a certified agent in late April, signing with Life Sports Agency. He'll be represented directly by Todd Ramasar.

The NBA Combine will take place June 21-27 and will see players participate in a variety of agility drills, scrimmages and lock in official measurements as they prepare for July's selection day.
