FAYETTEVILLE, Ark. — Arkansas has a new pair of sibling coaches.

Paul Petrino will be the Razorbacks’ offensive coordinator next season under his older brother Bobby Petrino, who was hired as Arkansas’ coach Tuesday after leaving the Atlanta Falcons.

Paul Petrino worked with his brother during Bobby Petrino’s 13-game stint as Atlanta’s coach. The younger Petrino was the Falcons’ receivers coach.

"I am really excited to be at Arkansas and be part of this great program," Paul Petrino said. "I’m looking forward to competing for championships."

Paul Petrino, 40, is six years younger than his brother.

Arkansas is no stranger to sibling coaches. Danny Nutt was the Razorbacks’ running backs coach for nine seasons under coach Houston Nutt before stepping down this past summer with health problems.

Houston Nutt resigned as Arkansas’ coach Nov. 26, but defensive coordinator Reggie Herring was named interim coach. Herring will coach the 25th-ranked Razorbacks in the Cotton Bowl against No. 7 Missouri, and most of Nutt’s staff has been kept around for that game.

Arkansas said Friday it received a waiver from the NCAA that allows the Razorbacks to add Paul Petrino without dropping anyone from the bowl staff.

Paul Petrino will recruit for Arkansas but won’t be part of bowl preparation.

Paul Petrino was an offensive coordinator and receivers coach under his brother at Louisville for four years before the two went to the Falcons. Louisville went 41-9 under Bobby Petrino.

"I am pleased to have Paul joining our staff at Arkansas," Bobby Petrino said. "He is a talented offensive mind and a valuable coach on the field and in recruiting. He was instrumental in the success we had at Louisville. I know he is excited about this opportunity and he will hit the ground running."
