Clark was arrested May 17 at his home on Nottingham Way and later indicted for felonious assault with a gun specification.
The gun specification, which could add to the sentence, was dropped as part of the agreement, according to court records.
Investigators said Clark shot his 24-year-old brother, Ky Clark, of Mooresville, Ind., in his left thigh during a heated argument at the Nottingham home.
Clark's 8-year-old son was reportedly sleeping in the residence at the time.
Clark faces a maximum sentence of 8 years and a $15,000 fine when he returns for his sentencing hearing in December.
