JOLIET, Ill. -- Rookie Jeb Burton and reigning Sprint Cup champ Brad Keselowski set the pace in Friday morning's pair of NASCAR Camping World Truck Series practices at Chicagoland Speedway.
Keselowski, still seeking his first victory in the series, led the opening 90-minute morning practice for Friday night's EnjoyIllinois.com 225 with a best lap of 176.085 mph. Keselowski, making his third start of the year in a Ford from his own race shop, will be attempting to join his father, Bob, as a truck series winner to become the only father-son duo to prevail on the circuit.
Burton, in the No. 4 Turner Scott Motorsports Chevrolet, clocked a 175.160 mph lap to lead the 50-minute final practice. The 21-year-old driver, fourth in the series standings, was also sixth-fastest in the opening session.
Ty Dillon, third in the series points, was second-fastest on the speed charts at 175.816 mph in the No. 3 Richard Childress Racing Chevrolet in the first practice, then registered the second-fastest lap in the later session at 175.182.
Kyle Busch, defending series champion James Buescher and four-time series champ Ron Hornaday Jr. completed the top five in the opening session. Justin Lofton, series points leader Matt Crafton and his ThorSport Racing teammate Johnny Sauter were third through fifth in final practice.
Austin Dillon, who won his only truck start this season on Eldora Speedway's dirt, subbed for Brennan Newberry in both practices. He drove the No. 24 Chevrolet to the eighth-fastest lap in both sessions. A member of the NTS Motorsports crew said that Newberry was being treated for a stomach ailment and that his status for Friday night's race was uncertain.
Keystone Light Pole Qualifying is scheduled for the truck tour at 4:05 p.m. ET (FOX Sports 1). The series' 16th of 22 races this season is scheduled for an 8:30 p.m. ET start on FOX Sports 1.
