FORT WORTH, Texas — Defending NASCAR Cup champion Martin Truex Jr. is starting from the back of the field in Texas.
Truex had qualified 13th, but moved to the back of the field for the start of Sunday’s race. His team made an engine change in the No. 78 Toyota after practice. He almost won last week at Martinsville to ensure the chance for a championship repeat before Joey Logano’s bump-and-run move on the last lap.
