The woman who claims she was attacked by boxing superstar Sergey Kovalev has now filed a lawsuit against the Russian … claiming the 35-year-old also brutalized her dog. It’s all in court docs obtained by TMZ Sports … Jamie Frontz (who has identified herself publicly) claims she met Sergey at the grand opening of a boxing gym in Big Bear, CA back in June. Frontz — a model and actress — claims Sergey and a friend followed her home from the party and Kovalev aggressively tried to have sex with her. “At one point, Kovalev pinned Jamie to the couch, leaning over her with his hands on either side of her shoulders, such that she could not move away.”Jamie claims her dog sensed the danger and tried to intervene — but Kovalev shoved the dog away and then kicked it in the chest. While tending to her dog, Jamie claims, “Kovalev turned to [her] and punched her with full force directly in the face one time with a closed fist.”In her suit, Jamie claims Sergey fled the scene — so, she called the cops. TMZ Sports broke the story … cops tracked down Kovalev and arrested him. He’s been charged with felony assault and faces up to 4 years in prison. Kovalev has pleaded not guilty. In her suit, Jamie claims she went to the emergency room where she was treated for a broken nose, head injuries and a concussion. She also suffered severe back and neck injuries. The next morning, Jamie claims she saw Kovalev crawl out of the bushes near her cabin, and he yelled her name — so, she called 911 and later got a restraining order against him. Jamie is suing for more than $3 million in damages. We reached out to Kovalev for comment — so far, no word back. Sergey is due back in court in March to face the criminal charge. He’s also set to fight Eleider Alvarez this Saturday, in a rematch of an August bout that he shockingly lost. View this post on Instagram I hear that he is denying on his social media that he punched me in the face. I\u2019m curious as to how he explains the fact that I suddenly wound up with a shattered nose, an open head wound, a concussion and two spinal injuries when he was standing 3 feet away from me in the living room of my own cabin (infuriated because I wouldn\u2019t have sex with him, so much so that he had just viciously kicked my dog Annie), and there\u2019s an eye witness who saw the whole thing. Nice try, Krusher. Fortunately, he\u2019s facing felony assault charges and I\u2019m also suing him for $8 million, so one way or the other I suspect the truth will come out. Sadly, I know all to well what its like to get punched in the face by Kovalev, only when he hit me he wasn\u2019t wearing gloves. . . . . #prettypinkacres #ranchliving #blondiestyle #farmlife #animallover #boxer #countrygirl #athlete #boxing #wbo #professionalboxer #assault #blondescandoanything #fighter #bigbearcalifornia #bigbear #strength #influencer #model #brandambassador #ownit #menwhohitwomen #truthwillprevail #courage #dogabuser #womanbeater #instareal #nomeansno \ud83d\udeab#factsarefacts #realtalk\ud83d\udcafA post shared by Jamie Frontz\ud83d\udc51 (@prettypinkacres) on Jan 29, 2019 at 9:41am PSTSergey Kovalev has been charged with felony assault for allegedly punching a woman in the face back in June — but he claims he’s not guilty … TMZ Sports has learned. Here’s what we know … the Russian fighter was arrested in Big Bear, CA on June 9 after a woman told police the former light heavyweight champion socked her in the face, causing serious injuries. Sources connected to the case tell us … the woman is claiming Kovalev had hit on her at a party earlier in the evening but rejected his advances. She claims Sergey and a friend followed her back to her cabin and that’s where the alleged attack occurred. We’re told the woman claims she suffered major injuries including a severely broken nose, a concussion and a displaced disk in her neck. FYI, Kovalev earned his nickname “Krusher” for his devastating punching power. 28 of his 32 wins have come by way of knockout. Cops tell TMZ Sports … they began searching for Kovalev immediately and arrested him a short time later. He was charged with assault by means of force likely to cause great bodily injury — which carries a maximum sentence of 4 years in prison. Kovalev appeared in court and entered a not guilty plea. What’s interesting … Kovalev fought Eleider \u00c1lvarez in August — just 2 months after the arrest — and lost in a shocking upset. Kovalev is due back in court in March. He also has a rematch with Alvarez lined up for Feb. 2. We’ve reached out to Kovalev for comment — so far, no word back.
