KENT, Wash. -- Former Seattle Seahawks offensive tackle Chad Wheeler has pleaded not guilty to criminal charges of first-degree domestic violence assault, domestic violence unlawful imprisonment and resisting arrest.

Wheeler entered the plea Monday morning during an arraignment at King County's Maleng Regional Justice Center. He was ordered to remain in Washington as a condition of his pre-trial release.

Wheeler was arrested Jan. 22 after his girlfriend accused him of twice strangling her into unconsciousness while he was experiencing what both called a "manic episode." According to a police report and charging documents obtained by ESPN, the woman said that when she regained consciousness for the second time, Wheeler verbally expressed his surprise that she was still alive. When asked by police if she thought she was going to die, she responded: "I thought I already had."

The police report states that when police forced entry into the apartment shared by Wheeler and the woman, she was crying in pain, with her face covered in blood and her left arm swollen and limp against her body. She also had noticeable fingerprints on both sides of her neck, according to the report.

Scans revealed a fractured humerus and dislocated elbow in the woman's arm, according to the charging documents. They stated that a scan of the woman's chest showed indications that she had aspirated fluid and that she vomited large amounts of blood the next day. She also reported a sore throat, difficulty swallowing and eating, headache and neck pain.

The charging documents state that the 6-foot-7, 310-pound Wheeler did not comply with officers' commands and that at least one Taser application was made directly to his body "with little effect."

The woman told police that Wheeler, whom she has been dating for about six months, has bipolar disorder and that he had not been taking his medication recently. She said Wheeler had a "manic episode" that was not provoked by any sort of argument but rather began when he suddenly "snapped into a dark place" and told her to stand up and bow to him. He grabbed her by the neck and threw her onto the bed when she refused, the woman said.

According to the charging documents, Wheeler texted the woman a picture of himself with a shaved head earlier in the day of the incident, which concerned the woman given that long hair is his "thing."

Wheeler has been ordered to have no contact with the woman and to surrender any weapons.

The Seahawks waived the 27-year-old Wheeler in the wake of his arrest. He was formally charged Wednesday.

In a series of tweets the same day, Wheeler wrote that, "Events happened over the weekend that transpired from a manic episode. I am deeply sorry for the pain and suffering that I have caused to [the woman] and her family. I apologize profusely for the turmoil that I have caused to my family, teammates, fans and those closest to me. The most important thing right now is that [the woman] gets the care she needs and I get help. Both are happening.

"It is time for me to walk away from football and get the help I need to never again pose a threat to another. I cannot express my sorrow or remorse enough. I am truly ashamed."

The Seahawks released a statement last week saying that the team is "saddened by the details emerging against Chad Wheeler and strongly condemn this act of domestic violence. Our thoughts and support are with the victim. Chad is a free agent and no longer with the team."

The team's statement also said, "We encourage Chad to get the help he needs" and asked anyone experiencing domestic violence or mental illness to seek help.

An NFL spokesperson told ESPN that the matter is under review of the league's personal conduct policy. ESPN has reached out to both Wheeler's agent and attorney for comment.

First-degree domestic violence assault is a Class A felony in Washington, while domestic violence unlawful imprisonment is a Class C felony. If convicted, Wheeler could be sentenced to eight to 12 years in prison, according to prosecutors.
