Hauser (COVID-19 health and safety protocols) doesn't appear on the Celtics' injury report ahead of Monday's game in Minnesota.
Though Boston will return Al Horford and Hauser from the protocols and potentially another key rotation player in Grant Williams (who is listed as questionable) as it begins a four-game week, the Celtics will be without star forward Jayson Tatum, who entered the protocol Monday for the second time in as many seasons. Even if Williams is ruled out ahead of the 8 p.m. ET tipoff, Boston will still have 12 other players available, so Hauser won't be a lock to be included in head coach Ime Udoka's rotation. Hauser, a two-way player, has made just three appearances at the NBA level during his rookie season.
