8:29pm: The roster moves are official, according to a team press release.
Jeffries will take Gabriel’s previous spot on a two-way deal, according to Ham. Rookie guard Kyle Guy has the other two-way contract.
Gabriel, 21, averaged 6.8 PPG and 5.4 RPG as a sophomore in 2017/18 at Kentucky but was not drafted. He signed a two-way contract with Sacramento last July, but has yet to make his NBA debut, spending his rookie season with the Stockton Kings. He averaged 4.8 PPG and 2.5 RPG in 12.9 MPG during four preseason games this fall.
