Celtics’ Jaylen Brown LOSES brand new NBA championship ring during parade… as he offers fans a ‘big reward’ for their help

Celtics star Jaylen Brown has already lost his NBA championship ring and is offering fans a reward for their help as he tries to get the hardware back.

Brown was named Finals MVP after leading the Celtics over the Mavericks in a series-clinching Game 5 victory on Monday.

But the forward apparently lost his ring just days later during the team’s championship parade on Friday, as he shared with fans the following evening.

The 27-year-old posted a photo of the jewelry on his Instagram Story and offered a “big reward” if they could find it.

He appeared to delete that story before posting a close-up of the ring on his hand.

He then posted a story with the same sentiment, while showing a closer look at the ring

“Reward for whoever thinks this ring lost him in the parade,” he wrote with an upside-down smiley.”

In a photo from the parade, Brown could be seen atop one of the parade floats pumping his fist, apparently without the ring on one of his hands.

The Celtics held a raucous parade for their home fans on Friday as Sam Hauser seemed worse for wear while sitting on one of the floats.

Celtics head coach Joe Mazzulla was also full of energy pumped out the Boston crowd.

Brown was extremely impressive in the postseason, averaging 23.9 points, 5.9 rebounds and 1.2 steals per game.

He also shot 51.6 percent from the field, the best mark of his career in the playoffs.

If a fan manages to find Brown’s shell and return it, they can certainly expect a decent reward.

The Celtics star signed a five-year, $286 million extension with the team last year and will make just under $50 million next season.
