UFC light heavyweight Modestas Bukauskas faces a career-defining fight Saturday at UFC 324 against Nikita Krylov. The Lithuanian's path to this moment began with a terrifying heart surgery at 19, where doctors induced palpitations while he was awake to fix a dangerous condition.

Bukauskas credits his father Gintas, a former Soviet No Holds Barred champion, for instilling his fighting spirit. After being cut from the UFC in 2021 following a knee injury and a difficult personal struggle, he clawed his way back with a four-fight win streak.

Now 31, a victory over Krylov could push the Baltic Gladiator into the UFC's top 15 rankings. Bukauskas views this as the culmination of his mental resilience, proving to himself and critics that his hardships have forged an unbreakable fighter ready for the spotlight.
