The Sacramento Kings waived KZ Okpala and signed P.J. Dozier for the rest of the season on Friday night.

Dozier was with the Kings on consecutive 10-day contracts.

Okpala is set to undergo season-ending knee surgery.

The Detroit Pistons have signed guard R.J. Hampton to a rest-of-season contract. Hampton was recently waived by the Orlando Magic.

Hampton has averaged 5.7 points in 13.9 minutes over 26 games this season. With Orlando having several other young, and finally healthy, guards, there was no longer a place for Hampton in the Magic's rotation.

Detroit is bringing Hampton in to take a look, as they play out the string in a rebuilding situation. This is the sort of bottom-of-the-roster churning that often unearths a solid rotation player moving forward.

The Cleveland Cavaliers have signed veteran wing Danny Green. Green recently reached a buyout agreement with the Houston Rockets following a trade deadline deal from the Memphis Grizzlies.

Green played in 43 minutes over three games with the Grizzlies before being traded to the Rockets. That action came after Green returned far quicker than expected from torn ligaments in his knee, suffered in last season's playoffs while playing for the Philadelphia 76ers.

The 14-year veteran started his NBA career with the Cavs back in the 2009-10 season. Green was a second-round pick by Cleveland at the 2009 NBA Draft.

The Denver Nuggets have signed guard Reggie Jackson to a rest-of-season contract. Jackson was recently waived by the Charlotte Hornets after being acquired in a trade deadline deal that sent Mason Plumlee to the LA Clippers.

In 52 games with the Clippers this season, Jackson averaged 10.9 points and 3.5 assists. He'll fill the backup point guard role for Denver, who traded Bones Hyland to the Clippers in a deadline day deal that brought Thomas Bryant to the Nuggets.

The move to Denver brings Jackson back home to Colorado. He played his high school ball at Palmer High School in Colorado Springs.

The Toronto Raptors have signed forward Joe Wieskamp to multi-year contract. Terms of the agreement were not disclosed by the team.

Wieskamp appeared in two games with Toronto earlier this season, while on a pair of 10 Day contracts. He averaged 4.5 points in 8.5 minutes per game.

In 19 G League games this season, Wieskamp averaged 16.7 points and 6.0 rebounds per game. He shot 49.3% from the floor, including 41.2% on 6.9 three-point attempts per game.
