Key Storylines

• Boston arrives in Indianapolis without Jayson Tatum, who remains out during his recovery from Achilles surgery, a season-long absence. Celtics star Jaylen Brown is listed as doubtful with low back spasms, meaning Boston could be down its leading scorer. Sam Hauser is questionable and Josh Minott remains out with an ankle injury.
• Indiana’s roster has been decimated by injuries, too. Tyrese Haliburton is out for the season with an Achilles injury, and Bennedict Mathurin will not play due to a thumb injury. Andrew Nembhard is questionable with back soreness, and Obi Toppin and Isaiah Jackson are listed as out.
• Boston has lost two of its last three games and was held to one of its lowest scoring outputs of the season in a home loss to the Spurs on Saturday. Despite that and the potential absence of Jaylen Brown, the Celtics still have dangerous scorers like Derrick White and Payton Pritchard who will try to pick up the slack.
• Indiana has won two games in a row after a long losing streak and a home victory over Miami recently provided a much-needed confidence boost. The Pacers are still one of the worst teams in the Eastern Conference and they will try to get back into the win column with a victory in this matchup from Indy.
