Arkansas football coach Bobby Petrino admitted in a statement issued on Thursday night that he hid details from the university about his motorcycle crash and Jessica Dorrell.

Petrino was put on administrative leave on Thursday after he admitted that he had an inappropriate relationship with Dorrell, which he initially tried to hide from public.

The 25-year-old female passenger with Petrino is an athletic department employee. On March 28, Petrino hired her as the student-athlete development coordinator. She is in charge of managing the recruitment process for the football team.

Petrino is married with four children Kelsey, Nick, Bobby and Katie. During a press conference Tuesday, two days after the accident happened on Sunday, Petrino did not mention he had a passenger.

A school statement released on Tuesday, quoting Petrino's family, said that no other individuals were involved in the accident.

On Thursday night Petrino admitted keeping quiet about Dorrell and also apologized to his wife Becky, his children and the University administration.  

Here is the full statement of Petrino via Arkansas Sports 360:

The state police report today provides an accurate description of my accident, which includes details that had not publicly come to light prior to the report being issued. I regret that I have not publicly acknowledged a passenger on the vehicle. I have been in constant pain, medicated and the circumstances involving the wreck have come out in bits and pieces. That said I certainly had a concern about Jessica Dorrell's name being revealed. In my press conference, I referred to her simply as 'a lady'. My concern was to protect my family and a previous inappropriate relationship from becoming public, he said. In hindsight, I showed a serious mistake in judgment when I chose not to be more specific about those details. Today, I've acknowledged this previous inappropriate relationship with my family and those within the athletic department administration.

I apologize to my wife, Becky, and our four children, Chancellor (David) Gearhart, Jeff Long, the Board of Trustees, University administration, my coaching staff, student-athletes and the entire state of Arkansas. I have been humbled by the outpouring of concern and get-well wishes. I apologize to the Razorback Nation for the attention my actions have brought to the University of Arkansas and our program. I will fully cooperate with the university throughout this process and my hope is to repair my relationships with my family, my athletic director, the Razorback Nation and remain the head coach of the Razorbacks.
