To say that Kyrie Irving is an unwanted man in Boston would be an understatement. Celtics fans despise their former star point guard and they have made their feelings about him abundantly clear — even during a Red Sox game that had nothing to do with the Brooklyn Nets superstar.

On Tuesday, the home crowd at Fenway Park started chanting “F–k Kyrie” right in the middle of the game between the Red Sox and the Toronto Blue Jays. I guess the fans were getting a little bit bored and they decided to turn their attention to the enigmatic All-Star point guard:

Apparently, this isn't the first time this happened. The previous day, the same melodious chant could be heard across the stadium as Celtics/Red Sox fans serenaded Kyrie with some unadulterated profanity:

Boston Celtics fans are some of the most ruthless in the world of sports and they just showcased their unwavering loyalty here.

The Celtics host Irving and the Nets on Wednesday for Game 2 of their first-round series, and you can be sure that Kyrie is going to get more than a few jeers throughout the game. The Nets guard is also coming off a $50,000 fine for flipping off a Celtics fan, so there's that too.
