Boston Celtics' fans held their breath on Monday night as Kristaps Porzingis limped off the court in the second quarter against the Miami Heat, clutching his lower right leg. The 28-year-old forward showed frustration as he made his way towards the Celtics' locker room with trainers, casting doubt over his return to the game.

Porzingis has been ruled doubtful for Wednesday's Game 5 against the Heat as he prepares for imaging tests on his right calf injury. While there is hope that he has avoided an Achilles injury, the team remains cautious about his condition.

The injury occurred in a non-contact situation when Porzingis pulled up after losing possession of the ball. Sensing the pain, he immediately signaled to the bench for a substitution. Prior to his exit, Porzingis had contributed seven points and three rebounds, helping the Celtics build a significant lead in Game 4.

In Porzingis's absence, Al Horford took over the bulk of the minutes at center for the Celtics. Despite losing a key player, the team managed to perform well and secure a victory in Game 4, giving them a series lead over the Miami Heat.

Considering the Celtics' advantage in the series, it is possible that they may choose to rest Porzingis even if he is healthy enough to play in Game 5. Losing him for an extended period would undoubtedly pose a significant blow to the team's title hopes, but they have shown resilience in his absence on Monday night.

Porzingis will undergo further imaging tests on Tuesday to assess the severity of his right calf injury. The Celtics and their fans anxiously await the results, hoping for good news and a quick recovery for their key player.

As Game 5 approaches, the Celtics must weigh the risks and benefits of playing Porzingis and assess the overall impact on their chances of advancing in the playoffs.
