The Celtics are starting Derrick White, Drew Peterson, Jayson Tatum, Neemias Queta and Luke Kornet against the 76ers on Thursday.
Boston was already shorthanded on Wednesday and will have even fewer options available against Philadelphia. Tatum and White are the only two typical starters available. Peterson will make his first start of the season, but Payton Pritchard will likely fill out more minutes after scoring 43 points on Wednesday.
