Indiana Pacers star Tyrese Haliburton managed to power through a calf injury he suffered in the middle of the NBA Finals against the Oklahoma City Thunder but the big guard appeared to reaggravate the issue in Game 7 on Sunday night.

Haliburton was already off to an incredible start to the do-or-die game for the NBA championship, nailing three 3-pointers in the first quarter to give Indiana an early edge. Haliburton was near the Thunder bench when he tried to drive toward his left.

He put the ball onto the floor with Thunder MVP Shai Gilgeous-Alexander on him. He appeared to slip and fall forward, losing the ball in the process. As the camera panned to Haliburton, he was down on his stomach, hammering his first onto the ground, writhing in pain.

The Pacers bench gathered around Haliburton as trainers attended to him. The game was paused for a few moments as Haliburton was helped off the floor.

Indiana said Haliburton suffered a lower right-leg injury and would not return.

Jonh Haliburton, Tyrese's father, said that his son had suffered an Achilles injury.

Haliburton had been the catalyst for the Pacers’ success throughout the playoffs. He made key shots in the first round against the Milwaukee Bucks, he brought heartache to Cleveland Cavaliers fans in the second round and sent a message to the New York Knicks in the Eastern Conference Finals.

In the NBA Finals against the Thunder, Haliburton continued to make huge shots to help the Pacers stay afloat against the league’s best team.

He was injured in Game but had 14 points in the Pacers’ Game 6 win on Friday night to force Game 7.

President Donald Trump on Sunday said there may be a regime change if Iranian leadership cannot "MAKE IRAN GREAT AGAIN," following strategic U.S. strikes on key Iranian nuclear facilities on Saturday.

In a post to Truth Social, the president questioned why there would not be a leadership shift following the devastating blow to the country's nuclear program.

"It’s not politically correct to use the term, ‘Regime Change,’ but if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn’t there be a Regime change???" he wrote. "MIGA!!!"

Earlier in the day, Trump announced the B-2 stealth bombers credited with strategic attacks landed safely at Whiteman Air Force Base in Missouri, applauding their efforts.

"The GREAT B-2 pilots have just landed, safely, in Missouri," he wrote. "Thank you for a job well done!!! DONA[L]D J. TRUMP, PRESIDENT OF THE UNITED STATES!"

The president added that the damage to the sites was "monumental," pushing back on skepticism from critics about the success of the operation.

"The damage to the Nuclear sites in Iran is said to be 'monumental,'" he wrote in a separate post. "The hits were hard and accurate. Great skill was shown by our military. Thank you!"

More than 125 aircraft were involved in the strikes in Fordow, Natanz and Isfahan, including seven B-2 stealth bombers, multiple fourth and fifth-generation fighters, dozens of air refueling tankers, a guided missile submarine and "a full array" of intelligence, surveillance and reconnaissance aircraft.
