Odell Beckham Jr. responds to Kyrie Irving's flat-Earth theory on Instagram

Cleveland Cavaliers guard Kyrie Irving made headlines last month when he revealed his personal belief that Earth is flat.

The sports world has continued to weigh in on the four-time All-Star's theory, with New York Giants receiver Odell Beckham Jr. becoming the most recent to poke fun at it.

In an Instagram post while accompanying Drake on the Canadian rapper's "Boy Meets World" European tour, Beckham Jr. posed in front of the show's main stage prop -- a large space orb. Although the sphere looks more like a sun than Earth, the three-time Pro Bowler couldn't pass up the chance to publicly educate Irving on some space science.

Beckham Jr. has attended several of Drake's concerts in recent weeks. Last year, he spent time living with the rapper at his Southern California estate.

Irving hasn't yet responded to Beckham Jr.'s jab. He entered Friday averaging 24.7 points, 5.9 assists and 3.3 rebounds per game for Cleveland this season.
