READY FOR EVERYTHING
UFC light heavyweight champ Jan Blachowicz says he's got a secret weapon for beating Israel Adesanya on Saturday night -- his newborn son!
The Polish powerhouse's fiancee gave birth to their first child, JJ, back in December -- and Jan says it's changed his whole outlook on life and fighting.
"Mentally, I'm stronger," 38-year-old Jan told TMZ Sports ... "Bigger motivation for everything right now. To hit harder, work harder."
"I do this for him right now."
As for his fight with Adesanya -- the undefeated middleweight champ -- Blachowicz knows it'll be the biggest challenge of his career but he's confident he'll end it in less than 2 rounds.
