Sept. 5 (UPI) -- Philadelphia Eagles defensive tackle Jalen Carter was remorseful after he spit on Dallas Cowboys quarterback Dak Prescott and was ejected from the NFL opener.

Carter spoke to reporters in the locker room after the 24-20 win over the Eagles' division rivals Thursday in Philadelphia. The Pro Bowl defensive lineman was ejected before the first snap of the night, creating a large void in the Eagles' defense for the remainder of the night.

"It was a mistake that happened on my side, and it just won't happen again," Carter said. "I feel bad for my teammates and the fans out there. I'm doing it for them.

"Not being able to start the game even, finish the game, it [expletive] me up but we're going to get it better. It won't happen again. I can make that promise."

The incident occurred with 14:54 on the clock in the first quarter. The NBC broadcast showed Carter approaching the Cowboys huddle and exchanging words with Prescott before spitting on the Cowboys quarterback. He was then ejected from the game for unsportsmanlike conduct. Eagles defensive tackle Moro Ojomo and Jordan Davis saw an increase in snaps due to Carter's absence.
