The backup quarterback replaced fellow rookie Geno Smith, who had thrown two interceptions and been sacked three times, in the fourth quarter during the AFC East side's 49-9 loss to the Cincinnati Bengals yesterday.
The 25-year-old told reporters: "I was very excited to go in, obviously not under those circumstances. Still, it was a good experience to get out there and just see the field, see the defense, get hit for the first time since pre-season. It was a good experience and now I've just got to go back to work.
"I was excited to be there, it was a spur-of-the-moment decision. I didn't have much time to think about it, running away from people trying to rip my head off. That was my first instinct.
"I'm probably going to get a few messages from my father [former New York Giants QB Phil Simms] telling me to be a little smarter in that situation. I just kind of wanted to show everyone that I'm going to sacrifice and play hard and play till the last play."
The Jets sit second in their division with a 4-4 record.
