Martin Truex Jr. joined the Chase for the Sprint Cup drivers suffering an early setback at Chicagoland Speedway on Sunday.
Truex led 30 laps early and was among race leaders when he had to make a pit stop for what turned out to be a flat tire. After the stop, he returned to the track in 22nd and was fighting fellow Chase driver Kevin Harvick — who lost a lap during a pit sequence in which he was on pit road when the caution came out and lost a lap — for the free-pass position should a caution come out.
