Jason Pierre-Paul played sparingly in the New York Giants' Week 1 loss to the Dallas Cowboys, coming onto the field on passing downs and picked up a sack.

"It felt like a preseason game. It was rough out there for me," Pierre-Paul said. "I didn't play to my expectations. Coming to Dallas, I play very well. But tonight was a struggle for me."

Pierre-Paul will be needed when the Giants play Peyton Manning and the Denver Broncos in Week 2.

"I wasn't tired, my back didn't hurt at all, I've just got to get into that football shape," Pierre-Paul said. "The next game is more serious than this one. We've got Peyton Manning coming through. I expect to keep getting better every day."
