The Celtics are still undefeated this season and will look to stay that way as they host the Bucks for a game at TD Garden on Monday at 7:30 p.m. For that game, rotation wing Sam Hauser was listed as questionable on the injury report due to back soreness.

Hauser has missed the last two games due to injury. He was questionable for the Wizards game before being demoted to the out. Hauser was originally listed as out for the Pistons’ game on the injury report. Kristaps Porzingis continues to undergo rehab surgery.

The Celtics are 3-0 this season and were coming off a narrow win over the Pistons on Saturday. The Bucks are 1-1 this year, beating the undermanned 76ers but losing to the Bulls. Milwaukee will also have a residual disadvantage as it faces the Nets in Brooklyn on Sunday, so the Bucks will play in a back-to-back game.

Despite Hauser missing the last two games, C’s coach Joe Mazzulla hasn’t adjusted his rotation too much. No substitute like Jordan Walsh has taken up those wing minutes as Mazzulla has opted to give more minutes to the big players. However, Hauser’s upgrade is positive as the injury does not appear to be serious and he has been getting it under control recently.
