Tragic news surfaced earlier this week that MMA fighter Joao Carvalho had passed away after a brain injury sustained in his fight with Charlie Ward at TEF1 Dublin this past weekend.

McGregor was ringside when Carvalho was TKO’d by McGregor’s teammate, which led the UFC featherweight champ to post this lengthy and extremely heartfelt message regarding the death of Carvalho on his official Facebook page.
