Louisville athletic director Tom Jurich confirmed that a former Wake Forest assistant coach-turned-broadcaster did share "a few plays" with a Cardinals assistant before the teams played last month.
Jurich said Louisville offensive coordinator Lonnie Galloway received a call from Demon Deacons radio analyst and former assistant Tommy Elrod before the game on Nov. 12.
Galloway and Elrod were assistants to Jim Grobe at Wake Forest from 2011-12.
Jurich said Elrod passed along the plays that were then shared with the defensive staff, but "none of the special plays were run during the course of the game."
Louisville coach Bobby Petrino said he had no knowledge of the situation, and team spokesman Rocco Gasparro said in a statement after the Louisville investigation was completed that Petrino had no comment "in what appears to be a Wake Forest issue."
