JACKSONVILLE, Fla. (AP) _ Unable to lure his first two candidates to Jacksonville, Jaguars coach Tom Coughlin ended up installing one of his favorite football minds as offensive coordinator: Himself.

Coughlin left the coordinator's spot open Wednesday, instead announcing the hiring of quarterbacks coach Bob Petrino, the former offensive coordinator at Louisville.

It confirmed that he has given up trying to fill the position Chris Palmer vacated to become coach of the Cleveland Browns.

``Now that our coaching staff is once again complete, we'll continue moving forward with our plans through free agency and personnel evaluations,'' Coughlin said. ``I'm excited to have Bob joining the Jaguars coaching staff and having him here as part of our program.''

Petrino will work strictly with quarterbacks and Coughlin will expand his responsibilities in an offense that he always played a significant role in _ including in the play-calling area.

Coughlin had interviewed former Bears coordinator Matt Cavanaugh and Broncos receiver coach Mike Heimerdinger for the coordinator's spot, but Cavanaugh took a position in Baltimore and Heimerdinger stayed in Denver.

Meanwhile, new defensive coordinator Dom Capers was introduced to media for the first time.

The former Carolina coach was hired last month to replace Dick Jauron, who became the head coach of the Chicago Bears.

Capers' hiring fueled speculation that the Jaugars will switch to a 3-4 defense next season. That was his specialty with the Panthers, and before that, as defensive coordinator with the Steelers.

He said a switch away from the 4-3 was anything but guaranteed.

``I think sometimes you get the label of being a 3-4 coach because of the Pittsburgh years and the first couple of years at Carolina,'' Capers said. ``But we always mixed the two, depending on what we felt we needed to do to win the game and how your personnel matched up against the opponent.''
