Lemon didn’t appear in any games with Boston, spending much of his time with the club’s G League team in Maine. He was signed to a two-way deal in July after spending part of the 2017/18 season with the Pelicans, where he played five NBA games.
Lemon, 28, went undrafted in 2014 after playing four collegiate seasons at Bradley. He averaged 22.4 points in 40 games with the Fort Wayne Mad Ants, G League affiliate of the Pacers, during the 2017/18 season.
The Celtics have started the season with an 11-10 record, struggling to gain chemistry on both ends of the floor. They’re set to host the 4-16 Cavaliers on Friday.
