Barrett (conditioning) is available and will start at small forward in Saturday's Christmas Day matchup with the Hawks, Fred Katz of The Athletic reports.
Barrett was considered a game-time decision, as the team was not sure if his conditioning was up to par. He was held out of the team's previous game due to that, but he been cleared to play Saturday. Do not be surprised if the team eases him back into the swing of things, however, head coach Tom Thibodeau is not known for exercising too much caution in terms of workload.
