The Boston Celtics' hopes in the 2025 NBA playoffs have taken a significant hit following the injury to star player Jayson Tatum, who suffered a torn right Achilles during Game 4 against the New York Knicks. The injury occurred in the fourth quarter of a game that ended in a 2-2 tie in the series, leaving the Celtics trailing 3-1 and on the brink of playoff elimination. Tatum's collapse on the court, compounded by his visible pain, has sent shockwaves through the team and the betting markets alike.

Before Tatum's injury, the Celtics were considered one of the favorites to win the NBA Finals, with odds of +225 at various sportsbooks. However, following their Game 4 loss and the announcement of Tatum's injury, their chances have plummeted dramatically. The Celtics are now listed at +3000 to win the championship, which places them among the biggest underdogs, trailing only the Golden State Warriors, who have also faced challenges this postseason.

The shift in the betting landscape has seen the Oklahoma City Thunder emerge as the clear favorites to claim the Finals, now at even-money odds of +100. This comes despite their own tough series against the Denver Nuggets, which is currently tied 2-2. The New York Knicks have also benefitted from the Celtics' misfortunes, now positioned as the second favorites at +500, while the Minnesota Timberwolves follow closely at +600 after taking a commanding 3-1 lead against the Warriors.

As the playoffs progress, the absence of Tatum raises questions about the Celtics' ability to mount a comeback in their series against the Knicks and highlights the volatility of playoff odds in response to key player injuries. The Celtics and their fans are left hoping for a miraculous turnaround as they prepare for what could be a decisive Game 5.
