The Boston Celtics and the New York Knicks will face off in the first game of the regular-season finale on Sunday at Madison Square Garden. The Celtics snapped their five-game losing streak against the bottom-ranked Minnesota Timberwolves in their previous game. Star player Jayson Tatum led from the front with 29 points and 11 rebounds as his side won 123-108. While the Boston Celtics cannot change their seeding, they will be hoping to end their regular-season campaign on a high note against the in-form New York Knicks.A double-double day for our @Gatorade Player of the Game. pic.twitter.com/rC1MRzLOQK— Boston Celtics (@celtics) May 15, 2021The Knicks continued their decent run with a 118-109 OT win against the Charlotte Hornets. Julius Randle was once again their best performer as he notched up a triple-double, tallying 33 points, 13 assists and 10 rebounds on the night. A win for the New York Knicks on Sunday and a loss for the Miami Heat would see Tom Thibodeau's men clinch the fourth spot and gain home-court advantage in the playoffs.The Knicks can clinch the No. 4 seed and a first-round matchup with the Hawks if they beat Boston tomorrow afternoon. If New York loses to Boston tomorrow and the Hawks and Heat win their games on Sunday night, the Knicks would finish 6th in the East.— Ian Begley (@IanBegley) May 16, 2021Boston Celtics Injury ReportBoston Celtics star Kemba Walker is sidelined due to a neck injuryThe Boston Celtics will once again be without several star players.
