EAGER TO MOVE ON from the Bobby Petrino scandal, Arkansas announced Monday that popular former assistant John L. Smith will return as interim head coach of the Razorbacks next season.

Smith, who left the Razorbacks after last season to become the head coach at Weber State, will be formally introduced on Tuesday. The school said Smith signed a 10-month, $850,000 contract and will also be eligible for other incentives.

Hiring Smith allows Arkansas athletic director Jeff Long to take his time to find a permanent head coach.

Smith was a head coach at Michigan State and Louisville. The 63-year-old leaves Weber State without ever coaching a game for the FCS school, his alma mater.

Weber State athletic director Jerry Bovee said the "timing of this announcement is problematic" but the school would move forward. Bovee did not immediately name an interim coach.
