After Dolphins linebacker Joey Porter picked up back-to-back 15-yard penalties late in the fourth quarter of Sunday’s loss to the Patriots, coach Tony Sparano had seen enough.

But when Sparano tried to pull Porter from the game, Porter refused to leave the field.

Porter is known for being a hothead, but a day later, he had cooled off enough to apologize. Adam Schefter of NFL Network reports that Porter personally apologized to Sparano and to the rest of the team, saying he knew what he did was wrong.

The Dolphins haven’t said publicly whether they’re going to discipline Porter, but all indications are that he will be on the field Sunday when the Dolphins take on the Rams.
