Bobby Petrino has been hired as the football coach at Arkansas. The announcement Tuesday night at Fayetteville capped a whirlwind day in which Petrino resigned from the Atlanta Falcons after just 13 games.

Petrino was hired to succeed Houston Nutt, who stepped down at Arkansas two weeks ago and became the head coach at Mississippi.

Petrino was introduced as the 30th Razorbacks coach by incoming athletic director Jeff Long at a late-night news conference.

In January, Petrino left as head coach at Louisville to take over in Atlanta. He agreed to a five-year, $24 million contract handed out by a team that felt he could help Michael Vick reach his full potential.

However, the star quarterback came under investigation for a dogfighting operation that led him to plead guilty to federal charges. Vick was sentenced Monday to 23 months in prison without ever taking a snap for Petrino.

Monday night, the Falcons lost to New Orleans 34-14, and hours later Petrino left the team with a 3-10 record to return to the college ranks.

He said Tuesday was a difficult day in one way, very easy in another. Petrino said it was difficult to leave Atlanta, the staff, players, fans, and the timing made it more difficult.
