After an impressive series against the Magic, Jayson Tatum and Jaylen Brown played one of their worst games in recent memory, and the Celtics dropped Game 1 against the Knicks 108-105 in overtime. Here are the takeaways.

Boston Celtics forward Jayson Tatum has been ruled out for Game 2 of the team's first-round series against the Orlando Magic with a wrist injury. Tatum suffered a right wrist bone bruise on Sunday during his team's 103-86 win over the Orlando Magic in Game 1 of their NBA Eastern Conference first-round playoff series.

The New York Knicks defied the odds Monday at TD Garden, coming back from a 20-point deficit and outlasting the Boston Celtics 108-105 in overtime of Game 1 of the Eastern Conference semifinals. The Knicks went on a 25-9 second-half run to cut the Celtics’ lead to four points with roughly 9 minutes left to play.
