EAST RUTHERFORD, N.J. (CBSNewYork/AP) — Jets Quarterback Geno Smith was caught on video losing his cool with a fan following Sunday’s loss at MetLife Stadium.

Frustrated after a third straight loss and calls for his backup increasing, Smith was caught by a CBS 2 camera shouting an expletive at a heckler in the stands as he walked off the field following a 24-17 loss to the Detroit Lions.

“Before we start this off, first of all I want to apologize if any kids saw me saying any negative remarks walking off the field,” Smith said to open his postgame news conference. “I kind of let my temper get the best of me in that situation, and it’s a part of my learning process.”

Smith had two more turnovers as chants of “We Want Vick!” filled the stadium at times, perhaps none louder than after he was intercepted by Darius Slay in the fourth quarter.

Smith’s teammates, however, came to his defense when asked about the crowd.

“That stuff, to me, is B.S.,” wide receiver Eric Decker said.

Defensive lineman Sheldon Richardson was even more blunt.

“Shut up,” Richardson said. “If that’s the case, produce a child who can come and make it to the NFL and let’s see what he’s got. Other than that, just shut up.”

Vick didn’t comment on the events, and coach Rex Ryan confirmed that, despite his struggles, Smith will start again for the Jets next Sunday in San Diego.

“No, I’m not going to replace him,” Ryan said. “I feel good about Geno. I think he will get it turned (around). He’s a tough, resilient young man. I think we’re going to win. We’ll win soon.”

Smith was 17 of 33 for 209 yards, including an 11-yard TD pass to Decker, but threw an interception and lost a fumble — giving him seven turnovers in four games.

Fans have been left frustrated, tired of the mistakes being made by the second-year quarterback.

Despite the skid and the struggles, the Jets players insist they still believe in Smith as the starting quarterback.

“He’s got to keep his composure, no matter how frustrated he gets,” Richardson said. “But it happens.”
