TALLADEGA, Ala. (AP) -- It all comes down to Kansas for Jamie McMurray.

McMurray’s day ended early Sunday at Talladega Superspeedway when he triggered a multi-car accident while attempting an ill-timed pit stop. He spun after he was hit from behind by Erik Jones. He left Talladega 12th in the playoff rankings, and only eight will advance after next week.

“We wanted to pit a couple of laps earlier, and you’re somewhat dependent on the spotters to tell you when you’re going to pit,” McMurray said after a quick checkup at the infield care center. “You assume everyone is working as a group. It was my fault.

“I assumed that they said the 18 (Kyle Busch) was going to let me in, so I thought we were all going to pit. I didn’t even know where the 77 was. When I got on the brakes, I thought we were all coming to pit road as a group. I’ll take the blame for that. I just kind of assumed we were coming to pit road right there. Obviously not everyone was.”

It leaves McMurray scrambling for positioning next week to advance and trying not to sweat the premature ending too much.

“There’s nothing you can do about it,” he said. “It’s part of Talladega. We know you can come out of here with a lot of points and be a winner or you can be in the position we are right now. We’ll go to Kansas and do our best. I’m sure I won’t be the only playoff driver disappointed today.”
