Iowa freshman guard Joe Wieskamp reportedly worked out with the Oklahoma City Thunder on Sunday, according to David Eickholt of Hawkeye Insider.

Wieskamp announced last month that he would enter the NBA Draft but would not hire an agent. By not hiring an agent, the 6-foot-6 guard is eligible to return to school next season.

Underclassmen that wish to return to school must decide by May 29.

Wieskamp averaged 11.1 points, 4.9 rebounds and 1.1 assists in 35 games for Iowa while he shot 56.4 percent from the field and 42.4 percent from three-point range.

In his first year at Iowa, Wieskamp proved to be a strong shooter after he finished fifth in the Big Ten in three-point percentage. Against Illinois on Jan. 20, Wieskamp recorded 24 points on 6-of-6 shooting from deep.

And some may still remember this shot:

Wieskamp is not currently projected to be drafted by any major NBA Mock Draft and is likely going through the NBA Draft process to receive feedback and evaluation on his game.

His decision to throw his name in the hat was apparently a surprise to some but it is a great opportunity for future prospects to gain valuable information on the overall process.

With the deadline for underclassmen to withdraw from the NBA Draft later this month, NBA teams are likely looking to meet with those players first before they return to school.

Some teams elect to publicly announce the prospects that they work out but, others, like the Thunder, typically keep that information private. Wieskamp is the first player to surface that has met with the Thunder.

With the Thunder out of the playoffs now, the team will likely ramp up pre-draft workouts with prospects. The Thunder have the 21st overall pick in the NBA Draft.
