No word on how many shares LeBron owns or how much money he put down -- but what's clear is he's a minority partner in FSG, which means he's a part-owner of the Sox, as first reported by the Boston Globe.

By the way, the Boston Globe is owned by John Henry -- the majority owner of the Boston Red Sox, who's reportedly worth $2.8 BILLION.

LeBron has publicly supported the NY Yankees for years -- but obviously, those days are over now.

LeBron has yet to publicly comment on the deal -- but he's expected to make some sort of announcement in the near future.

FYI, the Boston Red Sox are reportedly valued at $3.3 BILLION, according to Forbes ... which makes them the 3rd most valuable franchise in MLB, behind the Yankees and Dodgers.

LeBron has some experience with pro sports ownership -- he bought a piece of the legendary Liverpool soccer team back in 2011.

As for FSG, the company owns pieces of the NESN network, Roush Fenway Racing, Liverpool FC and more.

The move expands LeBron's already impressive empire -- he's reportedly made $343 million from NBA contracts alone.
