The Celtics have filled out their training camp roster by adding guards Ryan Arcidiacono and Garrison Matthews, an NBA source confirmed.
Arcidiacono, a former Villanova star, averaged 4.8 points and 2.2 assists per game and connected on 37.3 percent of his 3-pointers over four seasons with the Bulls.
Matthews spent the last two years on a two-way contract with the Wizards. He appeared in 64 games last year, averaging 5.5 points and making 38.4 percent of his 3-pointers.
The source said that the two players will likely be among a group vying for Boston’s second two-way-contract slot. Sam Hauser, a rookie from Virginia, signed a two-way deal this summer.
The Celtics open training camp next Tuesday.
