The 2015 myAFibRisk.com 400 was a NASCAR Sprint Cup Series race held on September 20, 2015, at Chicagoland Speedway in Joliet, Illinois.

This was Denny Hamlin's 26th career win, second of the season, first at Chicagoland Speedway and fifth at the track for Joe Gibbs Racing.

Jimmie Johnson entered Chicagoland tied with Kyle Busch and Matt Kenseth for the points lead at 2,012–points.

Kevin Harvick, Dale Earnhardt Jr., Kurt Busch and Carl Edwards entered tied for fifth six–points back.

Brad Keselowski, Martin Truex Jr. and Denny Hamlin entered tied for ninth nine–points back.

Jamie McMurray, Jeff Gordon, Ryan Newman, Paul Menard and Clint Bowyer entered tied for 12th 12–points back.

[13] When the green flag flies on Sunday, Jeff Gordon – who made his first career Sprint Cup Series start in the 1992 Hooters 500 at what was then Atlanta International Raceway (now Atlanta Motor Speedway) – tied Ricky Rudd's record for most consecutive starts at 788.

[15] Three rounds of knockout qualifying took place at 6:45 p.m., but heavy rain forced the session to be cancelled and the starting lineup was set by first practice times according to the NASCAR rulebook.

[19] Under clear blue Illinois skies, Kevin Harvick led the field to the green flag at 3:18 p.m.

The first caution of the race flew on the second lap when A. J. Allmendinger came down across the nose of Denny Hamlin and went spinning in turn 3.

By lap 15, Austin Dillon was pressuring him for the top spot, but got loose in turn 3 and lost the second position to Harvick.

Alex Bowman and Carl Edwards were both tagged for speeding on pit road and they had to serve drive-through penalties.

On lap 87, Kurt Busch, running fifth at the time, made an unscheduled stop after slamming the wall in turn 3.

The third caution of the race flew on lap 130 when Dillon blew his right-front tire out and slammed the wall in turn 2.

[23] His left-rear tire blew out and sent his car backwards into the turn 3 wall, bringing out the fourth caution on lap 137.

After drag racing through the front stretch, Kurt Busch passed his brother for the lead with 46 laps to go.

Kenseth hit pit road with 23 laps to go and the lead cycled back to Kurt Busch.

Gordon got a good start on Kurt, but he was passed underneath by Hamlin, forced up the track and ultimately finished 14th.

“Fast race cars are what we have and that was why we were able to come back and win today from that early trouble.”[31] "I'll tell you what, my guys just do a great job on pit road, they really do," Edwards said.

… We had a good day going and … cautions throw all that work out the window.”[35] "I knew we were going to have a tough time not spinning the tires," Gordon said about the final restart after a 14th-place finish in his record-tying 788th consecutive career start.

"[37] "I'm just really proud of everybody on our...team for not giving up and doing all the things they had to do to get the car back on the track," Harvick said after a disappointing 42nd-place finish.

We’ve got a reigning champion who finds himself in a tough spot … really needing to win (to advance), so you understand the frustration.

"[42] In his weekly appearance on the Sirius XM NASCAR Radio program The Morning Drive, NASCAR Executive Vice–President and Chief Racing Development Officer Steve O'Donnell told Mike Bagley and Pete Pistone that “there won’t be any penalties ” issued for the confrontation and explained the sanctioning body's reason behind the decision.

[43] Michael Waltrip Racing released a statement saying that it "respectfully disagrees" with the penalties and would immediately appeal.

"We look forward to the opportunity to present our case to the appeals committee and have no further public comment until the process is completed.

[44] On Wednesday, September 30, the National Motorsports Appeal Panel upheld the penalty levied against the team.

[45] The team decided not to make a final appeal and released a statement that said they were "disappointed with the outcome of today’s ruling and still feel our interpretation is within the guidelines.

Rather than continue the appeals process, MWR is ready to focus 100 percent of our company’s resources on winning at Dover and trying to advance to the Contender Round of the Chase for the NASCAR Sprint Cup.
