Leandro Barbosa arrived in Boston from Brazil and was working out prior to the Celtics’ 88-79 loss to the Philadelphia 76ers in their exhibition finale Sunday at TD Garden, although he is being delayed because of work visa issues. Neither he nor the Celtics know what role he will fill.
The Celtics signed Barbosa to a one-year deal for the veteran minimum to spell Courtney Lee, Rajon Rondo, Jason Terry, and Avery Bradley. Barbosa, 29, is not a natural point guard and might be lost in the shuffle once Bradley returns from shoulder surgery. Barbosa told coach Doc Rivers he just wanted to be part of a championship contender.
