What happened

Boston says it will be close to full strength for Tuesday’s opener in Detroit, but Devin Carter is out with illness after being diagnosed with mononucleosis and signing a two-way deal on Sunday.

The team said the rest of the roster is available, although the preseason starting five used in full-strength games is not yet confirmed as the regular-season formula.

LINEUP CONTEXT

Carter’s absence trims Boston’s backcourt and two-way depth, while the final opening-night rotation still appears unsettled. The preseason lineup looks informative, but the team has not locked in that starting group for the regular season.
