Celtics' Brown out; Tatum questionable for Tuesday's game

The Boston Celtics will face the Brooklyn Nets on Tuesday night without one of their All-Stars, Jaylen Brown. He has been ruled out due to a right knee impingement that also caused him to miss games last week. Brown left Saturday's game against the Nets because of back spasms. In that game, he scored eight points, grabbed six rebounds, and had three assists before leaving. Jayson Tatum is also uncertain for the game, as he is listed as questionable due to right knee tendinopathy. Tatum missed a recent game against the Utah Jazz because of his knee injury. Although the team has encouraged him to rest, Tatum has expressed his desire to play, especially in road games where he enjoys connecting with fans. On a positive note, Derrick White and Al Horford will return to the lineup after missing the last game. Kristaps Porzingis is healthy and expected to play, following his return from illness. The game is set to begin at 7:30 p.m. at TD Garden.
