CLEVELAND, Ohio -- The Cleveland Cavaliers have waived Billy Preston and Andrew Harrison -- a pair of players on Two-Way contracts, league sources told cleveland.com.

With those spots available, the Cavs have signed Jaron Blossomgame and Jalen Jones to Two-Way contracts.

Blossomgame, a 25-year-old forward, was a 2017 second-round pick by the San Antonio Spurs. He was recently acquired by the Canton Charge in exchange for John Holland.

In 11 games (eight starts) in the NBA G League this season with the Austin Spurs and the Charge, Blossomgame is averaging 20.7 points on 53.7 percent shooting to go with 7.6 rebounds and 2.3 assists in 32.6 minutes.

In five G League games with Canton, Blossomgame is averaging 17.2 points on 49.2 percent from the field and 38.1 percent from 3-point range.

Jones, 25, was a member of the 2017 D-League All-Star Team. After being waived by the New Orleans Pelicans last January, Jones spent the rest of the 2017-18 season with the Dallas Mavericks on a Two-Way deal, appearing in 12 NBA games while averaging 5.8 points on 13.5 minutes.

Given his NBA experience, it wouldn't be a surprise to see him stay with the Cavaliers for a few upcoming games, especially with David Nwaba still dealing with knee soreness and Sam Dekker set to hit the one-month mark with his injury Monday night in Brooklyn.

By rule, players on Two-Way deals act as a 16th and 17th roster spot. In the case of the Cavs it's the 15th and 16th. They can spend up to 45 days with the NBA team. But, according to a front office source, those days are pro-rated over the course of the season so the Cavs' two newest players can have up to 34 days in Cleveland.

Preston, an exciting 6-foot-10 forward and former McDonald's High School All-American, signed a Two-Way contract with the Cavs on July 7.

There had been recent internal conversations about calling him up from Canton while the Cavaliers were shorthanded. But ultimately, the team determined he was still too far away in his development and couldn't help with their immediate needs.

While the Cavs recognize Preston's untapped potential and the inherent risk in letting him go, he hasn't been able to put it all together playing in Canton.

In 10 games with the Charge, Preston is averaging 6.1 points on 35 percent shooting and 42.9 percent from beyond the arc, covering 2.1 attempts per game, to go with 3.8 rebounds.

Historically, the Cavs have given younger G League players opportunities to earn bigger roles and this is not different. Last February, they signed swingman Marcus Thornton to a 10-day contract.

Cleveland was looking at Harrison, a long-limbed point guard, as someone who could possibly earn the team's final roster spot. He was signed to a Two-Way contract on Nov. 9 and appeared in 10 of 11 games for the Cavs, averaging 4.3 points on 30.8 percent from the field and 21.4 percent from beyond the arc to go with 1.7 assists and 1.5 rebounds.

At the time the Cavs signed Harrison, head coach Larry Drew cited a need for an extra ball-handler. With George Hill back from his shoulder injury and the addition of Alec Burks recently, Harrison -- who did not play in Saturday's loss against Toronto -- became expendable.

Drew said following Saturday's loss that Burks would continue to share ball-handling responsibilities for the revamped second unit. That was the role Harrison previously occupied.
