LeBron James Sends Heartfelt Message to Caris LeVert After Gruesome Injury

9:30 AM PT -- LeVert reportedly dislocated his right foot and ankle in the incident ... and he can return later this season.

The NBA community is rallying behind Caris LeVert after his sickening leg injury on Monday ... with superstars like LeBron James and Paul George showing support for the Brooklyn Nets player.

LeVert went up for a block toward the end of the 2nd quarter against the Minnesota Timberwolves ... and he landed awkwardly on his right leg, which appeared to snap.

If you haven't seen the video already, it should probably stay that way. If you DO want to see it ... we warned you ... it's painfully gruesome.

"Young Fella prayers to you!" LeBron tweeted Monday night. "Speedy recovery and even stronger impact coming soon for sure!"

George added ... "God bless you youngin tough road ahead but we’re here to help lift you @CarisLeVert ! You know how to reach me"

"Prayers for Caris LeVert," Kevin Love tweeted. "Hate to see this. Having a hell of a season. Keep strong"

Gordon Hayward -- who also suffered a nasty injury last season -- offered his assistance in recovery ... saying "Best wishes and prayers to @CarisLeVert on a speedy recovery! The journey back is hard, but you’ll be stronger in the end. Please reach out if you need anything!"

FYI -- 24-year-old LeVert was having his best NBA season by far ... averaging 18 points a game.

LeVert was stretchered off the court and rushed to a Minneapolis hospital for treatment. Players in the game were so shaken up by the injury that some were reportedly crying in the locker room at halftime.

Chris Paul shared his sympathy, saying, "Prayers out to @CarisLeVert!!! Been watchin him play this season and I’ve loved every bit of it! Hate to see him get injured."
