State police said Friday they planned to question the trooper, looking for "any information Captain King might have learned about the crash" during conversations with Petrino.

"While the inquiries have no direct correlation to the investigation of the motor vehicle crash, the questions are legitimate and worthy of answers," state police spokesman Bill Sadler said. King has been asked to detail "his involvement with Coach Petrino and other individuals who've been identified within the crash investigation."

The developments came as Arkansas athletic director Jeff Long considered the future of the football coach, whose salary averages more than $3.5 million.

Long appears to have everything he needs to fire Petrino, but the question now is whether he actually will get rid of Petrino, who failed to mention having Dorrell with him during the accident and then admitted the two previously had an inappropriate relationship.

On Saturday, Long said he was working on the review of Petrino's conduct throughout the weekend and will likely work on Easter Sunday.

Long, met as he was walking out of the Broyles Athletic Center on Saturday morning, told The Associated Press the review process was "ongoing." He didn't offer a timetable for the conclusion of the review.

Petrino was not cited by state police, and was described by troopers as cooperative after the accident on a rural road 20 miles outside Fayetteville.

What has him in trouble is his attempt to keep anyone from finding out he was riding with Dorrell, a 25-year-old former Arkansas volleyball player who he hired just last week. A clause in Petrino's contract gives Long the right to suspend or fire the 51-year-old coach for conduct that "negatively or adversely affects the reputation of the (university's) athletics programs in any way."

That language gives Long plenty of leeway to punish Petrino, who is on indefinite paid leave after reviving Arkansas' football program over four seasons and, until now, steering clear of off-field blemishes.
