Debris has caused the second caution of Monday's NASCAR race at Chicagoland Speedway, slowing down the Chase opener at lap 70.
Kurt Busch took the race lead from younger brother Kyle (who had used a two-tire strategy on the last pit stop) at lap 41 and retained his advantage on the latest pit stop due to the caution.
There wasn't much to report since our last update aside from the lead change. Kyle Busch's two-tire strategy kept him in the top five, but it wasn't enough to keep him in the lead.
Greg Biffle has also looked strong (he's currently second), as has former leader Matt Kenseth (third) and Paul Menard (fourth).
Chase driver Jeff Gordon has surprisingly struggled so far today. He's been running from 25th-28th most of the race, but is now up to 23rd after the lastest pit stop. Denny Hamlin (21st) hasn't looked especially strong, either – but there's still plenty of time left.
There are 75 laps down, 192 to go.
