Tavion Thomas, a former running back with the Utah Utes, is reportedly in Salt Lake County jail and facing felony domestic violence charges stemming from an incident that occurred between him and his girlfriend last week.

According to The Salt Lake Tribune’s Kevin Reynolds, Thomas was booked last week and is being held without bail. A detention hearing is set for April 21. Thomas allegedly threatened his girlfriend with a knife, took away her phone and car keys, and said that if she called authorities she would be “dead before the police arrive.”

Thomas has been charged with one count of aggravated kidnapping in the course of committing unlawful detention, and two counts of aggravated assault, per Reynolds. All three counts are third-degree felonies, carrying maximum penalties of up to five years in prison if convicted.

Reynolds’ report also says this is the third time in the last six months that Thomas has been accused of being violent toward or threatening a woman.

The woman in question appeared in court this week and argued for his release, saying she does not feel he would “purposefully” hurt her and he needs treatment for bipolar and borderline personality disorders.

Thomas was in and out of the Utah football lineup last season, with coach Kyle Whittingham saying he needed to show more “accountability on and off the field.”

He lost his aunt days before Utah’s game against San Diego State on Sept. 17. The following week, he left Salt Lake City to return to Dayton, Ohio, where his aunt had helped raise him. Against Arizona State that weekend, Thomas sat out the first half though Whittingham said he was “available physically.”

On Oct. 15, Thomas was barely used in a season-defining win over USC. After the game, Whittingham said they’d “we’ll keep all that internal” when asked about Thomas’ status.

According to Reynolds, a witness told police she saw Thomas grab a girlfriend and drag her alongside a car on Oct. 23. (Utah was on its bye week that weekend.) The case was closed after the girlfriend told police she only had a verbal argument and, according to Reynolds, a police report stated she did not have any physical marks on her from the altercation.

Thomas did not travel with the Utes for their next game, at Washington State on Oct. 27.

On Jan. 8, a report of domestic violence from a woman in Bluffdale led to a charge of electronic communication harassment. According to Reynolds, a judge signed a temporary dating violence protective order against Thomas on Jan. 12, but the order was dissolved on Jan. 31 after neither Thomas nor the woman appeared for a court date.

“Tavion vehemently denies the allegations contained in the information filed by the State and maintains his innocence,” Thomas’ agent and attorney said in a joint statement to The Salt Lake Tribune.

Thomas declared for the NFL Draft on Nov. 25 and sat out the remainder of the season for the Utes. He participated in the NFL Scouting Combine in March.
