Several contenders were forced to the garage on Lap 25 on Sunday.
Danica Patrick was involved in a multi-car crash on Lap 25 at Michigan International Speedway after contact with teammate Jeff Burton. Although Danica was the 'trigger car' in the wreck, it appears that her teammate came down on her slightly, which sent her spinning out of control.
Patrick lost control of her car after going three-wide in Turn 2 and collected Martin Truex Jr., Trevor Bayne, Matt Kenseth, Justin Allgaier, Kyle Larson, Travis Kvapil, J.J. Yeley, and Michael Annett.
Larson sustained earlier damage in a pit road collision when Dale Earnhardt Jr. was exiting his pit box.
The race resumed on Lap 31.
