At the NBA Draft Combine, Upshaw measured as one of the tallest players in attendance (an even seven feet tall in shoes) with the longest standing reach and wingspan.

He was projected as a late first-round or early second-round selection,[5] but went undrafted, likely due to his personal issues.

In July 2015, he joined the Los Angeles Lakers for the 2015 NBA Summer League,[6] where he averaged a mere 1.4 points and 2.2 rebounds per game.

Upshaw felt there was more in him than his Summer League showing, and after dropping 20 pounds,[7] he signed with the Lakers for training camp on September 14, 2015.

In August 2018, Upshaw signed with Arka Gdynia of the Polish Basketball League and the EuroCup.
