Former UFC two-weight champion Conor McGregor posted a new tweet dedicated to the promotion's debutant Raul Rosas Jr.
"Raul Rosas - what a great debut, I'm watching you!" - McGregor wrote on his social media account.
The 18-year-old Rosas Jr. is by far the youngest fighter in the UFC. On December 11, he appeared on the undercard of UFC 282, where he faced compatriot Jay Perrin. Raul won this fight by submission in the first round. He has seven wins and no defeats under his belt.
