MACOMB, Ill.  -  Western Illinois University will play its second straight home football game Saturday when Illinois State visits Hanson Field for the 86th meeting between the two schools, continuing the oldest and longest-running rivalry in school history.  The 1 p.m. game will feature Illinois State?s league-leading passing offense versus the Gateway?s number-one pass defense, and will also highlight two of the nation?s most prominent players - Leatherneck running back Travis Glasford and Redbird linebacker Boomer Grigsby.The two teams are similarly matched, both coming off close victories a week ago and close losses the previous weekend.  Illinois State enters the game at 3-2, having a game at Florida Atlantic postponed due to hurricane threats, and Western Illinois is carrying a 3-3 record.  Both teams are 1-1 in the Gateway.  The Redbirds are averaging 268.0 passing yards per game while the Leathernecks have limited their opponents to a league-best average of 167.8 passing yards per contest, picking off 13 passes. Walter Payton Award candidate Glasford, who leads the nation in all-purpose yards per game (229.2) and ranks third in the country in rushing yardage (156.2 ypg), will be challenged by Buck Buchanan Award candidate Grigsby, who has compiled 47 tackles in his last three outings.  Glasford is just 29 yards shy of becoming the second-highest career rusher in Leatherneck history, a position currently held by Charles Tharp who rushed for 2,866 yards from 1999-2000.  Glasford is 961 yards away from Aaron Stecker?s school record of 3,799 (1997-98) career yards.  The Redbirds have allowed a 100-yard rusher in each of the last eight meetings. Last season against ISU, his only outing against the Redbirds, Glasford tallied 160 yards on 26 carries.Western Illinois has won seven of the last nine meetings with Illinois State, including the last three which have all been by 10 or fewer points.  The Redbirds last win at Hanson Field came in 2000, a 25-18 decision.  The Leathernecks lead the all-time series, which began in 1904, 45-37-3.
