TCU defensive end and Preseason Big 12 Defensive Player of the Year Devonte Fields is a suspect in a domestic disturbance that occurred Sunday morning in Fort Worth, Texas.

According to a Fort Worth police report, Haley Brown, Fields' ex-girlfriend, accused him of punching "her in the face one time with a closed fist."

TCU suspended the redshirt sophomore pending the findings of the police investigation, the school announced on Tuesday.

"I can confirm Devonte Fields is a suspect in a domestic disturbance call in Fort Worth, but we will have no further comment at this time," Sgt. Raymond Bush said Tuesday morning.

Brown, 20, was at the residence of mutual friend Kevin White and talking to him, according to the report, when Fields "punched White's bedroom window out with his hands from the outside."

Brown told police that she thought Fields had a gun and pointed it at her, yelling, "I should blast you!"

Police reported that Brown's right cheek was swollen and that she had "a small cut under her eye."

Fields had left the scene by the time policed had arrived, and Brown said she did not wish to press charges.

TCU head coach Gary Patterson spoke to the media about Fields' football accolades Monday and gave a lukewarm assessment of his selection as preseason defensive player of the year.

"I was kind of surprised Devonte Fields was [the pick] because he hadn't played a year ago," Patterson said. "I haven't watched him since you watched him."

Fields was previously named the 2012 Big 12 Defensive Freshman of the Year and the AP Big 12 Defensive Player of the Year after racking up 53 tackles and 10 sacks as a true freshman, but he only played in two games during the 2013 season because of a suspension and a foot injury he suffered during the third game against Texas Tech.

Despite his on-the-field brilliance, Fields’ time at TCU has been marred by off-the-field issues. In January the talented defensive end was attacked and robbed by three men who, according to a police report, pistol-whipped Fields before one of the assailants pointed a gun at him and threatened to kill him. Fields and the gunman got into a physical struggle during which five shots were fired into the air before his attackers fled. Fields declined to press charges. He was suspended for TCU's first game and part of the second in 2013 for a “violation of university and team policy” though the specific reason for the suspension was never revealed.

TCU did not respond to requests seeking comment.
