BOSTON — The Celtics will be without two starters on Monday night as they face off against the Utah Jazz at TD Garden. The team downgraded Jayson Tatum (knee) from questionable to out before tip. Al Horford (toe) was also downgraded while Kristaps Porzingis will remain out for the sixth consecutive game due to illness.

With a month left in the regular season, the Celtics are all but guaranteed the No. 2 seed in the East. Regardless of their standing, the Celtics remain the team to beat as they prepare for their title defense in the playoffs.
