"[He] grabbed me, bruised me, pushed me, made threats of more violence, left messages saying he would hire people to come and beat me with chains and bats," the papers claim.
According to the papers, Furlong was also allegedly using hard drugs.
"He is smoking cocaine and doing other various drugs. He is very unpredictable," Kneeland alleged.
The temporary restraining order prohibits Furlong from visiting their 3-year-old son, Ethan. Kneeland filed for divorce on July 6. A hearing to make the restraining order permanent is set for October 20.
However, in a statement to Access Hollywood on Wednesday, the actor's rep disputed the allegations, including the charges of drug use.
"Mr. Furlong vehemently denies all allegations that have been made and is currently working with his legal team to have this temporary restraining order extinguished," his rep said in the statement. "Unfortunately, the two parties are going through a very contentious divorce and custody battle. Eddie's main concern is his son, Ethan, and moving forward with his life. Eddie has been sober for more than five years and is preparing to begin production on a new film."
