Dewayne Jamal Dedmon (born August 12, 1989)[1] is an American professional basketball player who last played for the Ontario Clippers of the NBA G League.

Although tall and athletic, Dedmon did not play high school basketball until his senior year due to his mother's religious objections.

His mother, a devout Jehovah's Witness, refused to allow him to play organized basketball, believing it might affect his religious devotion.

[2] After turning 18, Dedmon, who had already grown to 6 ft 8 in (2.03 m), decided to exercise his age of majority rights and begin playing.

[2] After graduating from Lancaster in 2008, Dedmon attended Antelope Valley College as a part-time student and did not play basketball during the 2008–09 season.

[3] As a freshman at Antelope Valley in 2009–10, Dedmon, who had grown to 7 ft 0 in (2.13 m) tall, helped the Marauders to a 17–14 record while averaging 6.6 points and 7.8 rebounds per game.

Five days later against Victor Valley, he sustained a broken bone in his forehead and an injured nasal cavity when he was hit by an errant elbow.

[3] On April 14, 2010, Dedmon signed with the University of Southern California and subsequently redshirted the 2010–11 due to NCAA transfer regulations.

[4] As a redshirted sophomore for USC in 2011–12, Dedmon battled with numerous injuries which curtailed his development but still managed to average 7.6 points and 5.5 rebounds in 20 games (all starts).

[9] On November 1, he was acquired by the Santa Cruz Warriors of the NBA Development League as an affiliate player of Golden State.

[34] He made his debut for the Spurs on October 25, 2016, recording two points, eight rebounds, one steal and two blocks in 16 minutes off the bench in a 129–100 win over the Golden State Warriors.

[35] On February 10, 2017, Dedmon had 17 points and 17 rebounds, setting season highs in both categories, to help the Spurs to a 103–92 victory over the Detroit Pistons.

[47] Dedmon experienced diminished playing time as Richaun Holmes and Harry Giles moved ahead of him in the rotation.

[48] On February 6, 2020, Dedmon was traded back to Atlanta along with two second round picks, in exchange for Jabari Parker and Alex Len.

[49] On November 20, 2020, Dedmon was traded to the Detroit Pistons in exchange for Tony Snell and Khyri Thomas,[50] but was waived four days later.

Dedmon had gotten into an argument with Heat head coach Erik Spoelstra and threw a massage gun onto the court, resulting in him being ejected from the game.

[55] On February 7, 2023, Dedmon was traded, alongside a 2028 second-round pick, to the San Antonio Spurs in exchange for cash considerations.
