Kemba Walker (knee) out for Celtics in Game 4 on Sunday, Romeo Langford to start against Nets

Boston Celtics point guard Kemba Walker (knee) has been ruled out of Game 4 against the Brooklyn Nets on Sunday.

What It Means:

As expected, Walker has been downgraded to out and will not play against the Nets in Game 4 on Sunday. His next chance to play will come in Game 5 on Tuesday. With Walker sidelined, Romeo Langford will start on Sunday.

The Celtics are 8.5-point underdogs against the Nets in Game 4. Their implied team total of 109.75 points is the third-highest team total on Sunday's main slate, according to numberFire's DFS Heat Map.
