Celtics injury report: Jaylen Brown out vs. Bulls on Friday; three other Boston players listed with injuries

The Celtics' injury report Thursday ahead of their game against the Bulls was lengthy. But it didn't necessarily feature all bad news. Jaylen Brown was listed as out because of a right ankle sprain, which was expected. Tristan Thompson (left pectoral strain) and Romeo Langford (concussion protocols) were probable while Robert Williams III was questionable because of left foot turf toe.
