Celtics' Sam Hauser: Downgraded to doubtful

Hauser (adductor) is considered doubtful for Thursday's game against Detroit.

Hauser was previously listed as questionable, but he's trending towards being unavailable after being unable to return to Saturday's loss to Memphis. Jayson Tatum (knee), Jaden Springer (illness) and Jordan Walsh (ribs) are all considered questionable for Thursday, which could compromise the back end of Boston's depth.
