As you’ll see in this article, when their significant others get dragged into the middle of a feud, it can escalate. In those cases, the bad blood was taken to a whole new level. Check out 10 such instances here.

Donald Cerrone vs. Marcus Sursa

Light heavyweight Marcus Sursa used to date Donald Cerrone’s girlfriend (now wife), former ring girl Lindsay Sheffield. Things quickly got heated when the two crossed paths backstage at an Evolution Combat Sports event in New Mexico in 2010.

Sursa was fighting in the main event that evening. Cerrone was just a guest checking in on the warm-up of several teammates from the Jackson’s MMA camp When they spotted each other, words were soon exchanged. The two then began shoving each other, and Cerrone hit Sursa with a punch that cut his eye. Sursa split Cerrone’s lip in return. Due to the laceration he sustained in the skirmish, Sursa had to be pulled from his headlining fight later that evening.
