"(Summers) got an opportunity to go home and be with his family, which is a priority I can understand. I want to thank him and wish Mike and his family the best," Bobby Petrino stated from a press release through Arkansas Media Relations.
Summers is the son-in-law of former Kentucky basketball coach, Joe B. Hall.
In 2008, Summers tutored center Jonathan Luigs who was a finalist for the Rimington Trophy and an All-SEC selection.
Summers was on Petrino's staff all four seasons at Louisville (2003-06) and spent the 2007 season on Petrino's staff with the NFL's Atlanta Falcons as the offensive line coach.
In his last year at Louisville, three of his linemen earned first-team All-Big East Conference honors (Renardo Foster, Kurt Quarterman and George Bussey). Summers' line spearheaded the attack for a unit that ranked second in the nation in total offense (475.3 yards a game), seventh in passing (290.0) and 12th in rushing (185.3).
In 2005, guard Jason Spitz earned All-Big East honors, was a third-round NFL draft choice of Green Bay and started 13 games in 2006. Five other offensive players earned league honors, including tackle Travis Leffew. His 2004 line helped Louisville set a school record with 3,005 rushing yards and 47 touchdowns while allowing only 20 sacks and leading the nation in total offense. Louisville also set school records for total offense (6,468 yards) and points scored (597) with six Cardinals earning first-team All Conference USA honors.
In Summers' first season at Louisville, his line improved from allowing 46 sacks the year before (2002) to just 13. The Cardinals also set what was then a school rushing record, and ended the season fifth in the nation in total offense (488.9) and 10th in rushing (228.2).
Before going to Louisville, he spent two years at Ohio (2001-02) where his offense ranked No. 8 in the nation in rushing in 2002 (239.8) and No. 6 in 2001 (240.1). The Bobcats also allowed only 14 sacks in 2002 and 11 in 2001.
In 2000, he was the tight ends coach and recruiting coordinator at Oklahoma State. From 1997 - 99, he was assistant head coach and offensive coordinator at the University of the South, where his offense ranked fifth in the nation in rushing and second in the conference in total offense during his three seasons.
He was at Oregon State from 1991-96, where he was assistant head coach and offensive coordinator. The Beavers led the Pac-10 in rushing four straight years and he was named the league's top "Offensive Backfield Coach" in 1993.
He began his career at Kentucky (1979-81) and Texas A&M (1982-84), where he worked with the offensive line. He also spent six seasons at Northern Illinois (1985-90), coordinating an offense that set 51 school records.
Born June 16, 1956, the Lexington, Ky., native played defensive back at Georgetown (Ky.) College and earned his bachelor's in business administration in 1978.
He and his wife Kathy have a daughter, Amy, who is a Louisville graduate. Kathy is the daughter of legendary Kentucky basketball coach Joe B. Hall.
