The Celtics added a pair of players on Tuesday, signing Kelan Martin and Malik Fitts to 10-day contracts, according to Shams Charania.
Both Martin and Fitts have a real opportunity with the Celtics, who had three open roster spots after converting two-way forward Sam Hauser to a full-time deal. The Celtics now have 15 players under contract, including Brodric Thomas who is on a two-way deal.
Neither Martin nor Fitts is particularly well-known — Martin has played in just 93 games for his career including 27 this year, and Fitts has played in just 10.
