A pool cleaner claims she required surgery and will likely be scarred for life after Ezekiel Elliott's dogs violently attacked her in March ... and now she's suing the NFL star.
But Zeke's attorney tells us the NFL star adamantly denies wrongdoing and now he's digging in for a legal war.
It's all spelled out in new court docs, obtained by TMZ Sports, in which a woman says she went to clean Elliott's pool at his home in Frisco, TX on March 11 ... when she was "ambushed" by his 3 dogs -- a Rottweiler and two bulldogs.
