Hassan Whiteside is heading back to California.
The agreement - Monte McNair's first free-agent signing as the general manager of the Kings - is for the league minimum, according to NBC Sports California's James Ham.
Sacramento selected Whiteside in the second round in 2010 (33rd overall). He played sparingly over his first two NBA seasons before the organization waived him. Whiteside departed the league to play overseas shortly thereafter.
Upon returning to the NBA for the 2014-15 campaign, the North Carolina native emerged as a consistent double-double threat with the Miami Heat. He went on to play five seasons in South Beach before being traded to the Portland Trail Blazers ahead of the 2019-20 campaign.
The 31-year-old big man averaged 15.5 points, 13.5 rebounds, and an NBA-best 2.9 blocks in 67 games with Portland last season.
Whiteside is set to join a Kings frontcourt comprised of third-year forward Marvin Bagley, Nemanja Bjelica, and center Richaun Holmes.
