Despite insisting that he will play in Game 2 of the Celtics' second-round playoff series with the Philadelphia 76ers, the team announced Wednesday that Jaylen Brown is "doubtful" for Thursday's game.

The second-year swingman suffered a strained right hamstring in Game 7 of Boston's first-round series with the Milwaukee Bucks. Brown missed Game 1 against the 76ers, which the Celtics won 117-101.

"I’ll be back," Brown told NBC Sports Boston this week. "I'm playing."

"But there was some concern that I could re-aggravate it and it becomes a season-ending injury," Brown said. "I’m basically trying to come back in two days from a two-week type injury."

Brown is averaging 17.9 points per game in the playoffs this season.
