CONCORD, N.C. – Martin Truex Jr. was second fastest in Saturday’s final Monster Energy NASCAR Cup Series practice at the Charlotte Motor Speedway ROVAL, but it wasn’t all good news for the 2017 series champion.

Truex missed a shift midway through the practice after circulating the 2.28-mile course in 81.875 seconds at 102.009 mph. Truex came to a stop on the backstretch chicane and got a push back to the garage area, where it was decided that his No. 19 Toyota would need a new engine.

As a result, Truex will be forced to give up his eighth starting position for Sunday’s Bank of America ROVAL 400. He’ll now start at the tail of the 40-car field.

“I went from second to first (gear), so I don’t know. I’ve never done that before in my entire career, so definitely unfortunate,” Truex said. “I hate it for all the guys on the Bass Pro Toyota.”

Truex enters Sunday’s race locked into the second round of the playoffs thanks to two-straight victories at Richmond (Va.) Raceway and Las Vegas (Nev.) Motor Speedway.

“You know fortunately, I guess we don’t have a whole lot to worry about, it’s just frustrating,” Truex admitted. “We had a good car. We had a good qualifying effort yesterday. It’s just going to be hard starting from the back and I hate all the extra work for my guys. I apologize to them. I’m not sure how it happened. I had one other issue today with a shift in the gate. I don’t know if it was just an issue that was right there on the edge and I just screwed it up a little bit that one time, but we’ll have to look at it a little bit further.”

Another driver to have trouble during the final practice was second-place starter Alex Bowman, who lost control of his No. 88 Chevrolet coming out of turn three in the final minute of practice. He spun his car into a tire barrier at the entrance to turn four in the infield portion of the course, heavily damaging the right side of his car.

The damage was too severe to be repaired, forcing Bowman’s team to pull out a backup car. He’ll also have to start at the rear of the field alongside Truex. Denny Hamlin and Parker Kligerman, both of whom crashed and went to backup cars earlier in the weekend, will also start at the rear of the field.

Bowman, who was 10th fastest in final practice, enters Sunday’s playoff cutoff race two points behind polesitter and teammate William Byron for the final place in the next round of the playoffs.

Bowman’s Hendrick Motorsports teammate Jimmie Johnson also had issues in final practice, with the driver of the No. 48 losing control of his car entering turn five. He backed his car into a tire barrier, but his crew chose to repair the damage rather than prepare a backup car.

Austin Dillon also spun during final practice, but didn’t hit anything and continued with no damage.

Chase Elliott turned the fastest lap in final practice, topping the charts with an 81.801-second lap. Behind Elliott and Truex were Brad Keselowski, Clint Bowyer and Michael McDowell.
