Guy, who joins Tacko Fall, RJ Nembhard and others competing for the two-way spot, most recently played with the Kings. He appeared in 31 games last season, averaging 2.8 points in 7.6 minutes per contest.
Guy also won an NCAA championship with Virginia in 2019. He was selected with the No. 55 pick in the draft a few months later, signing a two-way contract with Sacramento after that.
The Cavaliers now have 20 players under contract ahead of training camp. Guard Brodric Thomas occupies the team’s only filled two-way spot.
